When Linda takes a picture of the gang, the feather on Isabella's helmet is black. When Isabella is shown after, it is pink again.
When Linda takes the picture, the graphics on the boards behind the kids are completely different.
In one scene, when the announcer raises his hand, you can still see the outline of his shirt collar through his hand.
When the Abominable-Inator hits the marshmallow and Doofenshmirtz's bottom, it should have made Perry larger with the marshmallow, and it should have made Doofenshmirtz's entire body grow.
Candace asks what a "disposable camera" is. In "Voyage to the Bottom of Buford", she buys a disposable camera to photograph the submarine. However, this could just mean "Voyage to the Bottom of Buford" occurs after this episode, as it has been confirmed by the creators that the episodes air out of chronological order. It could also mean that she'd forgotten since then.
After Major Monogram finishes giving Perry his assignment and Perry hops out of the chair, the chair front is light red without any stripes, rather than the orange shade it usually is, and does not have any lines.
Linda could've just stayed in her seat and used her phone camera or even Candace's or Lawrence's to take a picture of "kids on ice" instead of walking to the gift shop to recharge her disposable one.
When Doof asks the outdated moustache man what his resolution is, the man's head is in front of his tuxedo.
Major Monogram greets Perry with "Morning, Agent P," but it is nighttime. This is probably due to the fact that Major Monogram is on vacation elsewhere and forgot that he has a different time zone from Danville.
Isabella's scarf is darker.
At certain points in the episode, Isabella's scarf briefly changes to a darker shade of purple.
When Phineas says he's excited to finally see the New Year's ball drop, Ferb's hair is outlined with black instead of green.
Phineas and Ferb's ball lands way too early before the audience finishes the countdown. It should've landed at the final second while Doofenshmirtz uses the Resolution Change-inator on the audience.
Perry wears a tuxedo at the party in City Hall, but during Happy New Year, he isn't wearing a tuxedo while dancing with Doofenshmirtz.
Katie is nowhere to be seen during the kids' conga dance.
Just before the clock hits midnight, Candace is looking at Linda and Lawrence about to kiss in the courtyard. After the countdown and when the song begins, Candace is immediately on the dance floor waltzing with Jeremy. Linda and Lawrence have also appeared on the dance floor even though it has been about twenty or thirty seconds since they were in the courtyard.
As Phineas is pushing the lever to drop the ball, Adyson's sweater is red.
Gretchen, Holly, and Katie's sweaters were red when they started to enter the ball. However, when they're dancing throughout the song, their sweaters are orange, matching their Fireside Girls outfit. When they're leaving the ball, their sweaters turns back to red again.
When Phineas and Ferb begin to drop from the ball, you can see the Earth below and you can see that it is connected somewhere in Africa. (We know that Phineas and Ferb live in the U.S.)
The ball drop would've taken more than a minute as it descends from outer space and takes longer to drop from there. Therefore, the pole should've been 77 feet (23 m) long. (Although they do drop the ball before the one-minute-to-go mark.)
Throughout the whole of the episode, Adyson's hair is mostly colored black.
Up close, the Resolution Changer-Inator says "Resolution Changer-Inator", but zoomed out it is wordless.
At some points in the episode, Milly's hair is lighter.
During the close up of the three kids on the infinity slide in the song, they aren't wearing their coats, but when they join the conga line, their coats suddenly appear on them.
While the kids were watching the fireworks, if you look closely you can see Baljeet and three other kids have their eyes not outlined.
During the ten-second countdown to the new year, it actually took more then ten seconds in real life. Also, everyone didn't count down in ten seconds, it technically took twenty seconds.
When the camera shows everyone walking into City Hall, no one is wearing any coats.
When Linda and Lawrence enter the party, part of Linda's collar turns black for a split second.
The same shot of everyone walking into the party outside is used again when Doofenshmirtz arrives at the party.
When Linda has her coat on her hairband is black, but when she takes her coat off, her hairband is blue to match her dress.
When Candace and Stacy arrive at the party, Candace's hair is superimposed over the top of her coat.
If you look closely, an image of Doofenshmirtz and Perry dancing is on the New Year's Ball at the end of the song, which should only be possible if the boys know Perry's secret identity.
When Jeremy says "That's okay, I like you just the way you are", Candace's eyelashes are not filled in.
When Phineas pulls the lever to raise the ball, the lever is in front of him. But later, when he pulls the lever to drop the ball, the lever's location moves slightly to the left.
Bobbi's legs are missing and the bathroom is on the right position.
In the song, a scene pops up of a calendar on June. It folds back a month, but it shows a July calendar. It should have shown May.
Also, during the song, when Candace enters Bobbi's bathroom, his legs are missing, and only he is inclined, while the bathroom behind him is on the right position.
When Isabella, Baljeet and Buford start singing, for a second, one of Isabella's eyes are the same color as Baljeet's eyes.
After "Summer (Where Do We Begin)" one of Phineas' shoes turns green.
Isabella, Baljeet, and Buford were all absent when "Summer (Where Do We Begin?)", so they either shouldn't have had it in their memories (even if the Amnesia-inator didn't take out all of the memory from the movie), or they'd come up with the song outside of their idea, but Phineas would have remembered this. However, this could be explained if the song already existed prior to the movie.
With the above, when Phineas says "Yes, we all know the song", Perry's eyes are suddenly open as if in shock that they'd remember his secret.
Both Buford and Isabella mention projects neither of them were involved in. Buford mentions the Rollercoaster, but only Phineas and Ferb did that, although Isabella was a rider, and Isabella mentions the Portal to Mars, but only Phineas, Ferb and Baljeet built that. However, Buford could be mentioning the Rollercoaster in "Rollercoaster: The Musical!" and Phineas, Ferb and Baljeet had mentioned the Portal to Mars to Isabella at the end of "Unfair Science Fair".
Jeremy's odd map
The world map in Jeremy’s room shows several inaccuracies:
The Korean, Liaodong, Shandong, Malay and Baja California Peninsulas, along with the islands of Hokkaido and Timor, are missing from the map.
Iceland, New Zealand, Sri Lanka, Taiwan, and Madagascar are missing from the map.
The Mediterranean, Caspian, and Baltic Seas are shown to be landmasses connecting to the mainland.
Antarctica should've been shown as a landmass throughout the southern edge of the map. However, it is only shown below South America.
The eastern part of South America is overextended.
Only the northern edge of Australia is shown, while the rest of the continent is cropped and missing, including the island of Tasmania.
There is an unknown extension of landmasses in southern Africa.
Flies live more than seven days.
Perry is clean when he does a thumbs up to show that he approves of Doofenshmirtz’s painting. However, when the camera zooms out, both he and his hat are covered in paint. The grass is also dirty, even though it was clean when Doofenshmirtz finished the painting.
When Doofenshmirtz's painting is first shown, the face and the splotches of paint around it are blue, but the next time it's shown, the face and some of the paint turn red.
When she wakes up, Candace is wearing shorts. After she puts on her robe, the shorts becomes pants.
When Phineas and Isabella buckle up for the ride, Isabella's eyelashes briefly disappear.
For unknown reasons, in Spain this episode was named "Matón de ayudante" ("Assistant bully").
When Linda was coming home, she should have seen the Dental Hygienosphere from the front yard.
When Phineas, Ferb, and the gang first enter the ride, there are three carts. When they exit, there are only two.
When the ride starts, Phineas and Isabella's cart panel is blue, and Ferb and Baljeet's panel is orange. But the panels switch colors when they make the first drop, then they switch back after the 2nd drop.
When Doof ran to the -inator and said: "... looks like this is the end for you!" the mouse trap disappeared.
In the picture that Perry texts to Major Monogram for back up, Professor Bannister is missing his glasses. The text is also to Minor Monogram instead of Major Monogram.
The episode incorrectly states that the Canadian Constitution Act was passed in 1864, when it was actually passed in 1867.
At the start of the episode, when Perry is in Canada and Lyla tries to stop the burglars, Lyla is wearing her motorcyclist suit. When she gets off, she still is wearing the suit. However, when she says "Sorry.", she is in her normal clothes.
When Lyla and Perry fall off the roof the train, the train's whistle blows. However, the train's engine is very obviously a diesel locomotive, which could not possibly have a steam whistle. An air horn would have been more appropriate.
When Doofenshmirtz goes up to his Escape Platform, his hand with the Train Operator-inator passes through the edge of the opening.
A sign in Seattle at the beginning of the episode shows Interstate 13 North. The only interstate running north is Interstate 5. There are also no highways numbered 13 in Washington, nor is there an Interstate 13 anywhere in the country.
During Helicopter Fight, when Lyla's jacket is on, she's wearing blue pants and black boots. But when it comes off, they suddenly change into blue and black striped leggings.
As the screen pans down at the very beginning, the writing on the donut truck is reversed.
Also in one scene, the donut truck writing in a sideview mirror is printed forward and in another scene the donut truck writing says "delnery" instead of "delivery"
Hey, where's Perry?
Perry is absent from the overview picture of the Niagara Falls.
The first time the engine is shown, it has no rear truck (wheels), so it is floating. The only floating trains are seen in Japan.
When Bannister jumps out of the helicopter, he appears to be falling over suburban Danville instead of the Canadian mountains. However, the helicopter on which he and everyone else was on could have been flying over Danville at the time that he fell.
Major Monogram's monobrow is black instead of grey when they are in Niagara Falls.
When a Royal mountie put a criminal into a truck his suit is a Dark blue suit, rather than the red suit royal mounties wear.
During the first few close-ups of Doofenshmirtz in the train, the maple leaf pattern on the side extends onto the seat.
Doofenshmirtz says Niagara Falls is "close by" when he and the rest of the group were at the Canadian Parliament Buildings. In reality, Parliament Hill is in Ottawa, while Niagara Falls is near Toronto, which is, by car, over 5 hours apart driving. However, it is possible they would've passed by Niagara Falls on their way back to Danville anyways.
When leaving Niagara Falls, Peter the Panda is shown with a mouth and chin.
It is depicted snowing on the Canadian side. However, since the show takes place in summer, it couldn't possibly be snowing in Canada.
Bannister mentions annexing Canada to Greenland. This is very unlikely, as Greenland belongs to the Kingdom of Denmark, so in order to annex anything it'd have to get approval from the Danish government which would definitely rather have the Canada become another constituent of the Denmark instead of handing it to Greenland. This could also lead to big trouble with the British Commonwealth (which rules over Canada) as well as the US and NATO. Therefore, even if his plan does succeed, it'll lead to many times more trouble than what he planned for, and much more trouble than it's worth simply for 'national pride'.
In the credits, Trevor Simonsen's surname is misspelled as "Simsonsen".
Liam's surname is sometimes O'Cracken and sometimes McCracken. When Liam is first introduced he is named O'Cracken. He is also introduced as such in the promos. In the rest of the episode, however, they call him Liam McCracken.
Baljeet says that he is going to become president, but he cannot because he was not born in America.
Platypuses have a venomous ankle barb, not a poisonous ankle barb.
When Linda was at the fridge, she should've seen the machine out the window.
The number of Baljeets change throughout the episode.
When Candace first appears, her eyes are low on her face.
When Phineas says "That's very clever, second Baljeet.", the lower half of his face disappears for a single frame.
When Candace runs away immediately following that line, her body is cut off before she leaves the screen for a single frame.
The bus hits the clone Baljeet even before he walks on the road; in fact, the clone Baljeet is still walking on the sidewalk.
When Baljeet is about to split into two while in the kitchen, he is much smaller than usual.
When the Baljeet mob gangs up on Buford, the Baljeet that got hit by a bus and the Baljeet carrying the computer had disappeared.
When Liam first shows his boomerang collection, there are only a few boomerangs. He later produces more boomerangs, some of which were not shown.
Ice cream truck on wrong side of the road.
The ice cream truck pulls over on the left side of the road, but in the U.S., vehicles drive on the right.
Because the truck is on the wrong side of the road, the ordering window is put on the left side instead of the right.
When Buford mind switches with the alien the sclera of his eyes are red with a grid. During the square dancing his eyes look like everyone elses yellow sclera with red squares pupils. His sclera should have remained red.
During the "Square Dance", Candace sang, "if you're a reptile, four by four", but there are a total of five (three reptiles, a frog and a fly).
At the square dance, the two couples between Doofenshmirtz and Rosie only do-si-do and do nothing else.
When Doofenshmirtz and Rosie are dancing, one of the women has a bow on both sides of her head. However when Morg and his friends dance, the woman has a bow on only one side of her head.
When Ferb is programming the mind share device he is wearing two-finger gloves but when he runs onto the platform seconds later he is not wearing the gloves.
In the credits, Trevor Simonsen's surname is misspelled as "Simsonsen".
During the song, one of Phineas's eye disappears for one frame during the second chorus.
Lawrence had sprained his right arm, but when he was giving the speech, his left arm was bandaged.
Phineas the cyclops
In the end credits when Linda puts the pie in the sink, it appears as some of the frames were repeated because she puts her hands in the sink and then pulls her hands out and then puts her hands back in for a split second.
During the song, when Parry Gripp says "Rusted old drum" Buford has too dark freckles, which are also on the wrong side of his face.
The first time Candace says "Whatever" her mouth disappears during one frame and her hair is semi transparent, as part of it can be seen passing through her arm.
In this episode Francis Monogram's neck part of the uniform is light green instead of dark green.
When Phineas and Lawrence were making words with bee, Candace got angry and crumpled the magazine; then, some seconds later, the magazine is not crumpled anymore.
When camera zooms out to show Phineas as he answers from Isabella's perspective, Isabella is lit like she's on the beach she imagines later long before it. After Ginger snaps her from daydreaming, her skin becomes brighter again.
In the final shot of the Bee Song, some citizens appear twice.
When Doof takes out Mr. Tomato, the puppet is in front of the doorknob, but when it gets to closeup, the puppet is above the doorknob.
In "Bee Story", The Fireside Girls are seen as the few remaining ones from the bees before being sucked into the vacuum, and they are seen being separated from the bees when the bees are attacking Doofenshmirtz, yet these cases do not happen in this episode.
When Stacy shows the book to Candace near the end of the episode, she is holding the book upside-down.
At the beginning scene, Pinky doesn't appear. However, after Isabella enters the lodge, Pinky suddenly appears along with her.
When Isabella says "festivities are all over, we've got to get our beekeeping patches", Milly's expression seems to be angry.
During almost the whole episode, the diamond patch on Isabella's sash is orange instead of the usual teal.
While they're in the vacuum, Isabella tells Milly, Katie, and Gretchen to find the way out, and Ginger and Holly to make a sling for the queen. However, when she asks for a progress report, they've done the opposite tasks that they were supposedly assigned to (Milly, Katie, and Gretchen say that they've finished the sling, and Ginger and Holly say that they've located the exit).
When Isabella asks for sling progress report, as Gretchen, Milly, and Katie responses "All good to go!", all of their voices can be heard, but Gretchen's mouth doesn't move.
In one scene, Milly has the same eyes as Gretchen, but in the next shot, they're back to normal.
In Poofenplotz's L.O.V.E.M.U.F.F.I.N. rejection letter, it states the "F" in "MUFFIN" stands for "Fearsome" but it actually stands for "Frightening". Also, the "M" for "Maniacally" is missing.
In the same rejection letter, the first sentence is missing the word "inform". It reads "We regret to you..."
Poofenplotz says that L.O.V.E.M.U.F.F.I.N. is made up of men, despite women were seen in the past. However, she may just feel that the group is biased toward men.
Milly's hair is colored black instead of brown when the Fireside Girls are trapped inside the vacuum.
When Holly and Ginger report their progress, Ginger's legs are colored brown as her human look instead of black.
When Isabella and the Fireside Bees saw Doofenshmirtz, they should have also seen Perry, but Perry wasn't there.
When the Girls get sucked into the vacuum, Katie is nowhere to be seen.
In "Bee Day", Perry sprays the pheromones towards Phineas' and Ferb's giant wading pool, and all of the bees are seen going after it, hence destroying it in the process. However, in this episode, somehow the bees are all going to the Fireside Girls Lodge, though this may explain why some of the colonies fly separately.
Where's Katie?
When Pinky escapes from the handbag trap, the design on the inside of the bag is missing.
The ending sequence after Linda finishes saying that the wading pool reminds her of her childhood is extremely different than the one in "Bee Day". In that episode, after Linda finishes speaking, Isabella continues wading around, and Phineas does not greet her. In this episode, however, she instantly stops wading, and Phineas greets her. However, this could be explained if the producers "tuned out" one conversation for the purposes of the episode, or if they skipped past one to include the other.
The Queen Bee has eight legs instead of six.
When the Fireside Girls turn into bees, for some reason they don't have stingers on their butts.
In Poofenplotz's vision and when the Fireside Girls are being sucked into the vacuum, the bees look similar to actual bees, but every scene after, the bees are seen anthropomorphic.
Isabella's beret passes through her hair while the bottom edge of Milly's shirt is brown.
When the bee transformation starts to wear off, Ginger isn't present, but as soon as it has completely worn off, she suddenly appears out of nowhere.
In the song, when they sing "Everybody shake your rear end" Isabella's beret can be seen passing through her hair and the bottom edge of Milly's skirt first disappears for a single frame, and then, a few frames later, it turns brown for a single frame. Also, it appears that Isabella's right leg is outside the skirt as well.
The second time Ginger sings "Shake it, shake it, shake it, shake it, shake it, shake it, stop" the pattern on her shoes isn't outlined.
Near the end of the song, before the bees return to their hive, Isabella's dress is all orange on top. Usually, her Fireside dress is half orange and half brown, on top of a white shirt.
At some points of the song, the girls have inconsistent collars on their shirts throughout the song. At one point, Gretchen's shirt has a collar while her shirt is usually seen without a collar. Also, at one point, Katie's collar has the same color as her shirt, and later on, her collar is missing.
When the girls perform the "8" motion, Katie and Ginger are seen passing through each other, but somehow do not collide with each other.
When Doofenshmirtz turns on the vacuum and sucks in the bees, the Fireside Girls can be seen as a few remaining ones before being sucked in. However, in "Bee Day", they were not seen. When the bees are escaping from the vacuum, in "Bee Day", they weren't seen separated from the bees.
Phineas says the bee transformation wears off after a few hours, but only a few minutes have passed, though some time was unseen.
Technically, Holly is wrong when she says Candace had only earned 49 patches that day, since Candace was given a special patch for breaking the all-time record.
After Buford leaves, Baljeet's shoes are black instead of blue.
Director Dipthong's last name is misspelled, per the end credits. The proper spelling is "Diphthong".
While Candace is cooking vegetarian foods, her eyes are black instead of blue.
Candace mentions clogging, but neither she nor the two other dancers are wearing clogs. They are also not clog dancing; they're technically tap dancing.
Ferb switches from using a jet ski and a surfboard back and forth throughout the episode.
Melissa is briefly seen before everyone jumps into the water ball, but later on, she isn't seen on it.
Fluffy bites off Rodney's right hand. However, when he is holding the fake hand after, it is on his left hand.
When the water ball is in the backyard, the backyard is much larger than usual.
In the song, Candace can be seen walking and unicycling on a tightrope, standing on an airplane and a pyramid of girls, and dancing on top of an elephant, despite the fact she has a fear of heights. Maybe she had overcome her fear of heights from previous episodes.
When we see the grid of Candace's activities at the end of Extraordinary, after the line "I'll be a brand-new me", the lower right box disappears for a single second.
Despite this is the first episode to permanently show Candace has a smartphone, in the episodes where take place outside of the summer (e.g. "Happy New Year!"), it is shown that she is still using her flip phone.
According to the O.W.C.A. bylaws quoted in Perry The Actorpus, "No additional agents are allowed to thwart any single evil scientist if said first agent assigned is still well and able to carry out his duties." Yet, Perry and Pinky are teamed up for this episode's mission.
When reading down the elevator buttons, Doofenshmirtz switches the order of "Garage" and "Basement".
At the end of the song, when the women sing "History of the Tri-State Area!" they don't move their lips until the words "Tri-State Area" and never in the last "Area".
Pinky is in his old Season 1 design after reuniting with Isabella.
When Jeremy is explaining to Candace about Don, both of Candace's legs are in an impossible position.
When Doofenshmirtz types in the password for the computer lock override, he uses 19 letters, while reindeerflotilla uses only 16 letters.
When Don is looking at the “first diorama”, Vincent Diorama turns from a frown to a smile.
The will to the tristate area turns from a diploma-looking piece of paper in a frame, but however when the documents all get spilled the will turns to a piece of normal-looking paper.
Buford, as Alexander the Great, is shown as right handed, but, in real life, Alexander the Great was left-handed. Possibly that's because that's how Buford imagines it.
When Phineas and Ferb tie their starter portion via flips, it is clear when they approach the rope pile that the ropes are still separate exactly as they were before they started their ties. Possibly this is an intentional gag.
When Candace and Stacy are in Candace's room, Stacy had her bracelet. After Candace says she needs to think more like her brothers, the bracelet disappears.
Jeremy says that he met Candace is grade school, but Candace says she has known him since middle school.

Perry's "hair" is missing when he takes off his hat to get the proteins and carbohydrates.
When Doofenshmirtz starts explaining his plan in the gingerbread house, the window Perry is looking through is about knee to mid-thigh high on Doofenshmirtz, making Perry appear shorter. As Doofenshmirtz explains his plan, the window becomes waist high on Doofenshmirtz, restoring Perry to his proper height.
Candace said she was split into fifty, but in "Split Personality", she was actually split into thirteen (two at first, eleven more later). She could have been exaggerating.
Phineas said that he, Ferb and Baljeet took pictures with their smartphones (which only show their thumbs, parts of the chupacabra or nothing at all), but they didn't take out their smartphones to take pictures during the adventure.
Candace said she only has her trademark outfits in her wardrobe, but in "Flop Starz", she has various types of different outfits.
When Ferb is looking at the photos on his smartphone, he goes through photos 3 through 6, then goes back to 3. He should have gone back to 1.
When Doofenshmirtz calls Perry Señor pantalones inteligente (Mister smarty pants), he should have said Señor pantalones inteligentes, to have the noun and adjective agree in number. But then again, Doofenshmirtz is not very bright, so he might not have known that.
Phineas mentions the Lake Nose Monster, but he and Ferb were supposed to keep it secret.
The beam from the Switch Place-inator somehow gets into the house and into the crate.
The desert landscape is decidedly Arizona in origin. New Mexico does not have Bluffs or Socorro cactus.

When Phineas introduces Isabella to her birthday cake, Adyson's headband is the same color as her hair.
When Isabella starts saying "Butterflies? I love butterflies!", her mouth isn't moving.
When Isabella takes off her blindfold, her striped party hat falls off revealing her signature bow, she still has it when Buford bags her and takes her to the pool. Later, when the finale raises out of the pool, the hat reappears.
When Ferb brings the cake out, the candles are already lit, but then Ferb presses a remote to light them.
When the Fireside Girls are hitting the piñatas, as they shout "I'm gonna bash this thing!", you can see both Adyson and Ginger are mouthing it, despite only one voice was heard.
The stairway to lead Isabella up to the top of the cake suddenly appears from nowhere after the candles were lit.
After the candles spray confetti, Holly can be seen next to Adyson, but in the next shot she is next to Candace.
This also happens when the giant piñata is presented, she can be seen along with the other Fireside Girls, but in the next shot she is seen next to Candace.
When the finale gets turned into butterflies, look closely at Candace in the background; she walks in front of a patio post.
When the inator ray zaps the finale present, a teenage girl can be seen standing behind Adyson, but in the previous scene, she wasn't there.
When Candace dials Linda's number, she dials 6 numbers instead of 7.
When Stacy walks towards Dr. Doofenshmirtz covered in oil, the oily part of her hair bow turns transparent for a single frame.
When the Fireside Girls are first seen in Phineas and Ferb's backyard, Ginger isn't shown, but she eventually appears when the Fireside Girls are carrying a hood across the street.
Throughout the scenes when Doofenschmirtz is talking to Norm about approaching a woman the characters in the background constantly change where and who with they are standing.

Who is attending the booths changes and later the booths are un-attended.
Mardi Gras is usually celebrated in February, not in the summer.

The amount of mud on Candace changes one shot after another in the episode.
Doofenshmirtz's building does not rotate anymore when he starts to shoot Roger with his 90-Degree-Turn-inator, although the effect might not last long enough. Also, Roger is only seen rotating a few times at the beginning, and then he does not rotate anymore.
Phineas and Ferb have actually built an obstacle course before, their Super Skate Course of Doom from "The Beak", which had obstacles on it.
When Candace-Stacy and Isabella-Ginger teams reach the part of the course designed like a pinball machine, both teams duck rafts are red, whereas Isabella and Ginger's raft was green before and after the pinball area.
In this episode, it is implied that Stacy has never won a trophy. However, up to the third season, there are several times when Stacy is in her bedroom that you can see a huge trophy (probably for speed skating due to the figure on top and the speed skate hanging from her bed) and four gold medals hanging on her wall. Also, the Paisley Sideburn Brothers poster changes to a Bettys poster.
It is mentioned in this episode that Stacy never wins trophies, but she has trophies in her room in "Canderemy".

Right after the castle gets destroyed, Phineas and the gang instantly change into their regular outfits.
During "Troy", the lyrics state that Agamemnon got mad because Paris took Helen to Troy and started the Trojan War. This is false, however, as Agamemnon's brother Menelaus is the one that declared war on Troy because of the loss of Helen, not Agamemnon.
The first time Candace falls asleep while reading, she snores, but her mouth is closed.
Candace asks if there was something about a horse. Phineas responds in the affirmative. Actually, while the Trojan Horse is a story about the Trojan War, it is not described in The Iliad.
When Candace gets a soda to watch Phineas and Ferb re-create the Trojan War, the soda was in a blue and cyan plastic soda cup. But when she says "this is really cool" the cup she has turns into a glass cup with iced tea with ice cubes, not the soda cup.
When Candace was continually falling asleep while reading the Iliad, she only had a few pages read. But when she ran to the window to complain, The Iliad was half-way read.

When Candace says "Et tu, Vanessa?", she says it with a French pronunciation instead of the proper Latin.
Jeremy is first seen with auburn hair, but when the dance party begins, it changes back to his regular blonde.
In the first tale, when Candace is talking on the phone in the window, the "Me, Myself and I" poster is blank.
Soon after, when Candace is putting on her clothes, the figure of a heart is missing in the poster.
When Candace is putting on her shirt and skirt, she goes down out of the frame but when she gets back up, she is putting them on like a shirt instead of separately.
Also, when Candace is in front of her closet putting on her clothes (and on the phone with Stacy), she is bare foot, but when she walks to her bed to look under it, she is wearing her socks and shoes.
In the third segment, whenever Isabella is outside, the tint on her eyes is normal, when it should be darker.
When the gang is chasing the clones, for a moment, Phineas's bubble washer becomes transparent.
In the credits, Rusty Britches is erroneously named "Rusty Bridges".
When Phineas is telling the story, Perry intentionally kicks one of the evil platypuses but Phineas cannot be telling that part since he does not know about Perry's secret agent identity or his ability to fight.
When Buford poured grape juice on Perry, the juice covered half his left eye which should've hurt him.
Phineas wasn't holding Perry when he was trampled over by the clones in the grim ending.
When the camera zooms in on Phineas when he talks to Ferb about the foam city, his ear is outlined in black.
Baljeet does not use a metaphor; he uses a simile.
Before Isabella passes the foam barn, her socks are missing, but when she passes the foam fire hydrant, they are back on her.
Linda's eyebrows are missing when she looks up at the screen and sees the backyard.
Linda with no eyebrows.
When Candace says "This way, Mom", her mouth doesn't move.
When the giant foam town collapses, there should be some debris fall into the backyard as seen after Doofenshmirtz smashed its gear, but when we see the backyard from the screen, there are no debris.
When Vanessa encourages Doofenshmirtz to face the giant bat, her outline is colored brighter than usual.
After Candace sits down and starts typing, her right arm is superimposed over her hair.
In the first shot inside the Danville Space Laboratory, Linda, Jack, Candace, and Jeremy are walking together. When the camera zooms in on Linda and Jack, Candace and Jeremy are missing.
When the satellite shows the front of the Danville Space Laboratory, it appears to be nighttime, even though the episode is set during the day.
The size of Foamtown is inconsistent throughout the episode. When viewed from above, it's larger than the backyard and can be seen from the front yard. When viewed from the satellite, it's shorter and about the same size as the house. And when viewed from it, it's larger.
In the Disney Channel Australia premiere, the episode was titled "Face The Fear".
As Buford walks away stating he speaks sullen, Isabella's left sock turns transparent for a single frame.
When Phineas says "These should really make Jeremy's Birthday Scrapbook-aganza a full sensory experience" Isabella's eyes are black instead of blue.
When Doofenshmirtz shoots Perry with the Worst-Fear-Inator, Perry's card says, "O.W.C.A agent -- fearless," but, as shown in "Phineas and Ferb Get Busted!", Perry has a fear of being discovered and taken away from the Flynn-Fletcher family that is at least bad enough to cause nightmares. Maybe he had overcome his fear after discovering that, if his owners discover his identity, all could be solved with a memory-eraser (Phineas and Ferb the Movie: Across the 2nd Dimension). Perry was also obviously terrified of Doofensmirtz's driving in "The Doonkelberry Imperative", and he often looks scared whenever Doofenshmirtz inventions directly endangers his family, such as in "Journey to the Center of Candace".
When Doofenshmirtz is hit with the Worst-Fear-Inator later in the episode, he says that nothing bad will happen as long as you don't think of anything scary. If Perry managed to not think about anything scary when he was hit by the ray, it could explain why none of his fears showed up.
When Phineas and Ferb prints the flower image, Baljeet is missing.
The scrapbook shows pictures from "Happy New Year!", that actually, hadn't happened yet at the time of the episode.
Two episodes references which do not aligned with each other
The Scrapbook-aganza pictures from "At the Car Wash" shows Adyson and Holly were riding the giant scrubbers, but some shots later, Holly is replaced by Ginger. Also, the Scrapbook-aganza version of Candace and Jeremy were riding through the car wash shows them wearing their "My Sweet Ride" outfits instead.
When the Worst-Fear-Inator zaps Candace, Isabella isn't shown in the group shot. After the Scrapbook-aganza flies away, Isabella appears out of nowhere.
Near the end of the episode, Isabella is seen wearing her watch, although earlier she wasn't seen wearing it at all.
Near the end, when Candace is upset her worst fear has come true, Candace's scrapbook can be seen next to Jeremy on the ground, and Jeremy appears to be holding it even though he's cut offscreen.
During the credits, the box that shows the scene was smaller than usual when it began.
While the Lumière brothers were in fact the earliest pioneers in filmmaking, there is no historical evidence that they ever came to America, let alone Danville. But of course, this is all in the interest of comedy and is not meant to be taken seriously as a historical reference.
Pneumatic Pnorman states that he cannot bend over to pick up a coin without throwing his axles out of alignment, yet earlier in the episode he bent over to pick up Sweary the Swan.
Adyson, Gretchen, and Katie lookalikes wear their sashes on their right shoulders instead of their left, unlike their present counterparts.
As Monty Python would tell you, tennis with five people is not really considered doubles.
When Doofenshmirtz finishes explaining his plan, the ball at the inator's tip disappears.
Doofenshmirtz's mouth does not move when he is talking while simultaneously placing Perry in his truck.
At one point during the song, Isabella's socks are longer than usual.
Phineas and Ferb and friends use gadgets avoid incidents is considered lucky and Doofenshmirtz fails to zap Roger with his invention due to Roger getting distracted by the sleeping Perry and Doofenshmirtz accidentally waking him up is considered unlucky, but Doofenshmitz, Phineas, and Ferb swapped their luck. It's possible that the Stinkelkrampen-Inator may have a few glitches.
When Candace passes The Johnson's house, the mailbox is seen with the writing "The Johnsons", but when the camera zooms over to Suzy, the writing disappears, and then reappears after the scene is zoomed out.
When Doofenshmirtz and Perry are driving to the mayors office, Perry was originally in the back of the car, but then switches to the passenger's seat.
Did he really fall asleep?
Perry is seen awake once when the truck drops its almond brittle cans to Doofenshmirtz's car.
When Doofenshmirtz enters Roger's office as he brings Perry inside the cart, Perry is seen still wearing his seat belt. When Roger is about to greet the sleeping Perry, the latter doesn't wear his seat belt anymore.
Isabella and Buford do not hold their helmets on their hands, nor they do put their helmets on the grass at the moment when the inator effect starts to wear off. Later on, their helmets reappears near the ladder, along with Phineas and Ferb's helmets. When the crack swallows the structure, the helmets disappears, and then reappears again after the crack is sealed.
After Isabella hits the baseball, Phineas's glove switches from his right hand to his left hand. When Buford and Baljeet arrive, the glove is back on his right hand.
When Buford says "You're goin' down, dweeb" the inside area of Gretchen's glasses are darkened instead of clear.
When Candace turns around to realize Linda's driving away, she smiles very quickly.
Gretchen and Ginger were the only Fireside Girls participating in the game, but when the jetpacks carry the batting cages away, all of the Fireside Girls are there.
Everyone is standing next to each other when the Big Idea explodes into fireworks, but when in close up of everyone astounded, no one is surrounding them.
When Candace runs to Linda's car, it appears she's heading for the car's right side, but in the next shot, she runs to the left side.
Also, at the same time, the car is instantly in its parking space and the trunk is instantly open even though the car was still parking in the previous shot.
After Linda realized she didn't bring her groceries and went back to her car, she drives back to the store without even closing the trunk first.
When the batting cages took off the wagon with baseballs is still there, but somehow neither Candace nor Linda saw it.
The angles that were drawn by Baljeet will not be accurately correct if measured by protractors in real life.
When Candace and Linda are first seen shopping, Linda does not have a cart. When she calls Candace, she suddenly gets a cart full of groceries.
When Isabella announces Buford and Baljeet are tied, Gretchen is shown to have 50 strikes but when Isabella announces it will go into sudden death, Gretchen's strike counter is changed to 60.
Buford, Baljeet and Ginger's strike counters stay the same instead of changing.
The jet that pulls Candace hovering. V.T.O.L (vertical take off and landing) jets do not have a fixed rear jet engine in that position.
In the establishing shot of the casino, Doof's hands are on the table. However, when it cuts to Doof, his hands are holding up cards.
When Doofenshmirtz lands in the pool, the man cleaning the pool says, "Gladys, j'ai une autre." The subtitles reveal that the man said, "Gladys, we have another one," but "j'ai une autre" actually translates to English as "I have another one."
The period in the "Doofenshmirtz Evil Inc." sign is accidentally replaced with a comma.
Rodney appears with the other scientists at the beginning of the second fight with the O.W.C.A. agents but should not be there since he is with the inizer headed to the roof of the building.
It's meant to be a joke because they are using the exact same animation from the earlier fight.
When the gang sings "Come on and rock the curve", the knobs on Isabella's bass disappear.
During the Summer in Northern Hemisphere, Antarctica's time should've been mostly at nighttime, although in some northern parts of the continent, a brief daytime may still occur.
When Buford beats a drum in the Alps, his arms disappear.
When L.O.V.E.M.U.F.F.I.N. threatens to move the Earth further away from the sun unless the City of Danville meets their list of demands, Doofenshmirtz demands pretzels, despite the fact that it is revealed in Buford Confidential that Doofenshmirtz despises pretzels.
Monty pronounces Rodney's last name as "Rodden-STINE" (so that it rhymes with "line"), but it was previously pronounced "Von Rodden-STEEN" (to make it rhyme with "clean") by both Rodney himself and the announcer from "Great Balls Of Water".
When Candace says “Those stupid kids never knew what hit em’!” Closed Captioning doesn’t caption “stupid“.
Candace is revealed to have a fear of spiders, but in "Gaming the System", she fights spiders in one of the video game levels. It's possible that this episode occurred before "Gaming the System". Or maybe she wasn't scared of the video game spiders because they were fake.
Shortly after Phineas appears as a hologram to Candace in the attic, when the camera goes behind Phineas, he clearly has five fingers instead of the usual four.
It's seen to be that there are spiders and spider tanks in Danville Insect Emporium. However, spiders aren't insects, so there shouldn't be any spiders there.
When Perry gets trapped, the rope is yellow. Later on, the same rope trapping him is silver-brownish.
Before and as the rain begins, all of the kids are seen riding their respective kites. Later in the scene, Ferb and Isabella are with Phineas in his kite, and Baljeet is inexplicably on Buford's.
The bird that was seen flying to Ferb's kite becomes smaller when Ferb releases it from his kite.
On Disney+, the captions incorrectly spell Isabella’s name without the 'a' after Phineas asks if everyone is ready.
During "Punky Momo", when the blue haired guitar player is first seen, her guitar is pink. Later in a close up, her guitar is yellow.
When the Fireside Girls carry Irving into the clubhouse, his shoes are a different size, shape, and color. Also, if one looks closely, Holly and Milly's berets are missing when they carry him in.
When Isabella peeks at the mail truck behind a bush, she is wearing her Fireside Girls uniform but without the sash. When the camera zooms in on her skateboarding, she's suddenly switched to her regular outfit. In every scene after, she switches back to her uniform.
Isabella can change outfits by pulling on her belt, which may explain the sudden outfit change ("Night of the Living Pharmacists").
Isabella is not wearing her sash while skateboarding, but after sneaking into the Mail Depot her sash suddenly appears on her body.
At multiple times during the song, Isabella's shoes are brown instead of red.
During "I Need My Letter Back", Adyson is sucked into a chute, but when she emerges at the other end, she is relatively smaller than when she went in.
When Phineas approaches the mailwoman when she is about to give him the letter, Adyson's eyelashes disappear. Also, in the next shot, the order the Fireside Girls were standing in changed.
There are two Millys visible.
During "I Need My Letter Back", when the lyric "A full-scale rejection" is reached, there are two Millys visible for a couple of frames.
When Phineas starts reading the letter, the envelope apparently disappeared.
At the very end of the episode when Isabella yells at Milly, the far edge of her beret is superimposed over her head.
Monogram says he's a Sagittarius, which means his birthday is between November 22 and December 22, but he celebrates his birthday sometime during the summer as in "Backyard Hodge Podge".
Mercury only goes retrograde for about three weeks at a time. Although the date of this episode is uncertain, it's likely the summer has been going on for a lot longer than that by this point.
The driver's side of the mail truck is on the left. However, the door is on the right and near the end of the song "I Need My Letter Back", the mail woman enters the truck from the right also.
When Phineas first reveals the art piece to Isabella, all the kids are lined up on the left including Baljeet and it is apparently finished. However, when he's explaining the details, Baljeet is now adding pepper flakes to The Blue Boy.
When the Isabella and the Fireside Girls got in the Post Office, Gretchen and Milly are missing.
Perry's "hair" is missing when he takes of his hat to get the nickel.
During "I Need My Letter Back", the mail truck's stripe changes from blue to orange as it drives into the Mail Building. Also, just before the truck enters the building, the rear stripe slides slightly upwards. There is also one frame in which a portion of the stripe turns blue.
Additionally, the text "Mail" changes from red to black,
There's an error shown in this image. On the left, you see the pizza still on the bench. At the right, you see that the pizza has disappeared.
Right before the hologram turns Candace into a pizza boy, she is seen without her shoes and socks painting her toenails. However, when its effects wear off, her shoes and socks reappear.
In the bleachers, when Jeremy and Coltrane's friend says "What?", the pizza's on the same bench as Candace. Though, when Coltrane says "I have a feeling", when Candace says "Great. Let's hear it", the pizza's gone off the bench.
The dinosaur Doofenshmirtz transforms into does not resemble Velociraptor, lacking both feathers and the sickle claws on its feet. In fact, it is identical to the orange dinosaurs briefly seen in "Phineas and Ferb's Quantum Boogaloo".
In Star Wars Episode IV: A New Hope, the Imperial Officer on the other end of the com-link said, "We're sending a squad up." Here he says, "We're sending a squad in."
On the closed captioning, Jawas are credited with the screen with the scream during the "Sith Roast Decaf" bumper, not R2-D2 as originally heard.
It happens again when Norm-3PO screams like R2-D2, but the captions says "Ewoks screaming".
Phineas gained an extra arm.
When Perry the Rebelpus escapes carbonite, he should have gotten hibernation sickness, rendering him blind. However, his vision is great while he fights Darthenschmirtz.
When Phineas watches as Darth Ferb destroys his lightsaber, there is an error in the animation, causing him to have two left arms.
Before Ferb gets hit with the Sith-inator, he has his hood on over his head and it flies off when he gets hit. After he gets hit and lands on the ground, his hood is back up.
Darthenshmirtz tells his backup dancers to prepare for a victory number in Act IV if the Sith-Inator succeeds, which does not make much sense because at the point in which he is saying this, the episode is nearing the end of its fourth act.
At one point, Phineas said to Candace, "Don't shoot him, he's my brother!" Although Phineas already told Candace, Candace still asked why Ferb is hugging them after Candace realized that she got reunited with her brother.
Also, although nobody had specified to her yet, Candace somehow knew that it was their mom but not their dad that had remarried.
After Darthenshmirtz escapes from the carbonite while on Agent P's ship, he calls Agent P "Perry the Platypus," when he's called him "Perry the Rebelpus" throughout the episode.
Before the Capsule opens, the kids are standing in a line, but while it opens they are standing in a circle. The chainsaws on their feet also disappear.
During "Talk to Him" six chorus girls enter the door, but at the end, only five of them leave (maybe she left out of screen or after the other five, while Doof was talking with Professor Mystery).
When Bernie starts explaining the consequences of opening the capsule and when the kids are holding onto the tree, alternate dimension Phineas only has three white stripes on his shirt instead of four.
Aliki Theofilopoulos Grafft's name was misspelled in the credits as "Aliki Theofilopoulous Grafft" in early airings of the episode. It has since been corrected.[1]
When Ginger starts her verse in "Jump Right to It", Isabella's eyes briefly turn brown, then back to her blue eyes again.
When Isabella first seen in the backyard, somehow there is another Flynn-Fletcher's house in the background. Also, the road leading to the backyard is seen similar to a paved road instead of the usual white driveway road.
When the gang are leaving to Fireside Girls' Lodge, Phineas' rubber vest is red, but when they left for the alley, it turns back to grey again.
When Vanessa goes to put a bookcase in front of the door, Candace's belt is missing.
Dana was first seen wearing a gray tracksuit and white rubber shoes, but in later scenes she is seen wearing a black sleeveless shirt, gray skirt, and black boots.
In the scenes when Phineas is taking questions and Candace shoves Vanessa out of the way, Vanessa is missing her gloves.
After Isabella tells Phineas how she feels, the orange of her shirt changes white as her sash moves. As if her sash was changing the color of her shirt, but when she goes to climb the ladder her shirt is normal again.
At certain points in the episode, the diamond patch on Isabella's sash turns orange.
During certain points, a character's blue eyes turn black.
After Phineas examines the Repulse-inator, the Emotional Bravery Patch on his arm matches the color of his suit.
When Doofenshmirtz explains his schemes to Perry, the sky briefly changing colors.
As Isabella presses the button on the vortex sprayer, her arm is seen transforming into a Doof zombie arm, and a lab coat growing on it. In the next full-body shot of the transforming Isabella, her arm is still her own and "pharmacists" with the rest of her body all over again.
Additionally, based on the position of her thumb, she presses the button with her right arm. In the next shot, her left arm is extended.
Multiple errors
When the Fireside Girls turn back to normal:
Gretchen's head is abnormally large.
Katie's cleats have red circles near the foot holes and she's wearing socks when she shouldn't be.
Adyson is seen wearing a shirt with sleeves instead of her usual sleeveless shirt.
Milly's hair isn't even wet.
Before Phineas and Ferb get infected, the Doof Zombies take off their hoods and goggles; when they turn back into themselves, they are wearing them again.
It is possible they put their hoods and goggles back on after they changed back, but before they came to the top of the water tower.
When Roger transforms, his glasses fall off and the lenses break. When he transforms back, the lenses are fine but the left arm is bent.
Unless their batteries ran out before or at the same time the electricity went off, Ferb and Candace's cellphones should not have turned off.
Candace is lit like it's daytime, and Isabella's skirt turns orange
Several characters are seen brighter than the other characters on multiple cases during the blackout scenes, despite there are no lights.
When Phineas and Ferb are standing by the destroyed Repulse-inator with Candace and Isabella, Isabella's skirt has the same color as her top.
When the Fireside Girls disguise themselves as pharmacists, Gretchen is on Ginger's shoulders, Holly on top of Adyson, and Katie on Milly, but the next scene afterwards, Milly and Adyson have swapped places.
When Doofenshmirtz decides his patience has reached its end with his zombie lookalikes, he strips down to his underwear. Once everyone is back to normal, he is clothed again.
Without getting touched?
Before Lacie get infected, there are numbers of Doof zombies behind her. When she get infected as Vanessa and Candace runs away, apparently there are no zombies behind Lacie.
When Doofen Zombies throw Doofenshmirtz out of his building and enter it again, the hair of one Doofen Zombie briefly turns gray.
In "Jump Right To It", at one point Ginger's hair disappears.
In the second verse of "Jump Right To It", Gretchen gets on a table and continues singing. However, the table is not shown in the previous shots or later shots.
Several times during "Jump Right To It", the Fireside Girls' heads are abnormally large, and when Ginger starts her verse, her hair is much shorter than usual.
Ginger's eyelashes disappear in the songs "Jump Right to It" and "Triangulation".
No triangulation is actually done during the song "Triangulation". Triangulation requires a known distance and two measured angles to a specific point. Isabella instead uses similar triangles or basic trigonometry to pinpoint Doofenshmirtz's building. Also, the line Isabella drew that connects the "weird impression on that wall" to the DEI building appears too high above the point where Roger stood.
Also, Roger was in front of a curtain when he was hit with the ray, not a wall.
During "Triangulation", at one point Adyson and Ginger have no patches on their sashes.
When The Fireside Girls sing "That could pinpoint the conclusion of my scientific quest" Milly's whole face is cropped.
Perry can fly?
Perry is briefly seen flying without holding his glider, right after Monogram and Carl are turned into zombies. He first lifts his right hand to look at the clock on his arm. Then he lifts his left hand too, to turn off the clock. Despite this, he doesn't fall, and he keeps moving forwards in the same speed as the glider (judging by the animated background).
The rules for what counts as "touching" are inconsistent.
Several characters graze against lab coats multiple times without changing. Later on, Gretchen changes when she comes into contact with a zombie's legs, but she was most likely pulled by one of the newly transformed Doofen zombies instead.
The Fake Andrews Sister in the center was touched by the other singers as they transformed, and later the same thing happens to Dana as she's surrounded by Heather and Birgitte. Similarly, Linda changes as she's holding Lawrence's hand after he shakes hands with a zombie. However, a transforming Phineas hands Isabella the clamp for the vortex sprayer without causing her any harm.
When Beppo Brown gets transformed, his paint pallet was dropped on the ground in the close-up. After the camera is zoomed out, the pallet disappears.
At one point, the inside of Vanessa's shirt turns green like Buford's, when it is normally black.
As the power static caused by the zombie contact turns the infected victims into pharmacist zombies and visibly turns them wearing lab coats, some of the victim's wearings (such as sunglasses wore by a pilot, and fedoras (wore by the O.W.C.A. agents)) are not affected, though the Fireside Girls sashes and berets, as well as all of the victims' outfits prior to their contact with the zombies, are all affected.
In "Bee Story", it's said a Fireside Girl only gets two chances to earn a patch. Since it took Isabella more than two tries to talk to Phineas, it's possible she can't try to earn the Emotional Bravery patch anymore. However, since their memories were erased after building the vortex spray it could still be possible.
Candace says "When does it ever rain here?", though in several episodes ("Hide and Seek", "The Great Indoors", etc.), rains were actually happened throughout Danville, although she's possibly thinks that the weather is barely raining in Danville.
When Doofenshmirtz helps Perry to escape with a helicopter, which later becomes boarded by Agent Bear as well, it seems like Perry forgot to raise the ladder, though in the next scene, after both Doofenshmirtz and Perry are boarding the helicopter, the ladder is already lifted up.
During the Gordon Gutsofanemu, when a woman gets affected by a pharmacist, the pharmacist's teeth disappears and then reappaears after the woman is affected.
Between the commercial break at Part II, Isabella's color tone becomes darker in the second part.
When Gretchen and Ginger enters the Fireside Girl Lodge, the space seen through the opening of the coat between Ginger's hair and Gretchen's chin is grey. Then, in the next scene Gretchen's shirt and sash can be seen there, but as they start to remove their disguise, Ginger's beret suddenly blinks in front of the shirt and sash.
When Perry gets infected, the electric sound effect isn't heard.
This is later fixed on Disney+.
Perry's arm is beige
Perry's arm is beige while holding the almond brittle can.
Unless the entire Doof zombies were all venturing outside, it is unknown how the sprayer affects Doof zombies whose is still indoors, though the zombies were already breaching most of the indoor spaces throughout the city.
Phineas, Ferb, and Isabella can hear Dr. Doofenshmirtz shouting when they were on the pulley system to the water tower. However, they should not know what his associations are with Perry when he shouts "No, not Perry the Platypus!" as Perry lives a different life with Dr. Doofenshmirtz than he does with them, and Major Monogram erased their memory of Agent P in "Phineas and Ferb the Movie: Across the 2nd Dimension".
However, this ultimately isn't an issue as the kids lose their memories of everything from building the vortex sprayer to being changed back.
Milly's voice actor (Isabella Murad) is not listed in the credits even though she does have a speaking role.
When Isabella, Phineas, Ferb, Baljeet, Buford, and the Fireside Girls all run to get to the building, Milly is wearing a pharmacist hat.
Doofenshmirtz mentions that Charlene left him due to his voice, but in "Bee Day" it was said that it was due to "Mr. Tomato".
When the Vortex Sprayer changes everyone back it is dawn. In the next scene at Stacy's house it's still the middle of the night.
When Candace enters the cell block, she is shown taking off her glasses. But when she is shown from behind, you can see the arm of said glasses, which implies that she may have put them back on.
When the gang fights the robot agents to save Perry, Peter's eye briefly turns red instead of white.
When Pinky's metal falls from his body, the metal covering his ears falls too, despite the fact that he used them as a spinning blade earlier and thus should have been entirely mechanic.
Also, even though his metal parts fell off, he is seen later on with them on again.
Throught the episode, the claw on Peter's robot arm changes size at random intervals.
Monogram mentions that, counting Perry, they have lost 26 agents (the english alphabet letters), but actually, there are more agents than alphabet letters because, there are agents such as "Agent Silent G" and 3 Agent Ps (Perry, Pinky, and Peter).
Of course, there may be letters (such as U, Q, X) that don't have corresponding animal agents, although there are animals starting with each letter of the alphabet.
Irving has no speaking lines, yet he is credited in the End Credits.
Milly is not present with the other Firestorm Girls when they escort Doofenshmirtz.
During the song "All the Convoluted Reasons We Pretend to be Divorced", when Charlene is singing the line "So to avoid a situation with such limited appeal", her cornea can briefly be seen, with a red dot on it.
During "All the Convoluted Reasons We Pretend to be Divorced", when the word "Convoluted" is said for the first time, the subtitles say "Convolutes".
When Vanessa and Lacie are talking before class starts, in one of the scenes Lacie's dress is black rather than red.
How did he change back into his usual clothes?
When Doofenshmirtz is about to get onto Perry's hoverjet, he is wearing his outfit with a green shirt and purple tie, but when he is on Perry's jet, the outfit changes to his usual black shirt.
The calendar during the "Doof 101" song shows July ending on a Wednesday, August starting on a Tuesday and ending on a Thursday, and September starting on a Sunday. Additionally, July 31st is missing.
At one point in the background, the chalk board says that the square root of 42 minus 2 plus 1 is equal to infinity, which is obviously not true. The actual answer is about 5.481.
When the camera zooms out the class, there are three rows of seats, but when the camera zooms in to Doofenshmirtz there are only two rows, then changes to three again, and after Johnny gets mutated, it becomes two again, and Vanessa's row eventually goes to the front.
Buford says that Isabella came to Phineas and Ferb's house every day for eleven years, but she does not show up for some projects in the summer the timeline takes place in ("La Candace-Cabra", to name one).
In What Might Have Been:
Tween Isabella standing on teen Isabella's foot.
In Isabella's part, when her young adult, tween, and preschooler selves sing backup, tween Isabella's right foot is standing on young adult Isabella's left foot.
When we see Isabella entering the backyard in her toddler, kid, tween, and teen ages, if examined closely, it seems that she somewhat becomes the same size as the fence.
When Phineas is giving Isabella a flower, the insides of the bottoms of Isabella's pants become superimposed over her shoes.
Phineas has freckles on his head when seen as a toddler, kid, and teen, but when seen as a preschooler and tween, he does not have them.
When the gang are in the backyard, Adyson's hairband repeatedly disappears and then reappears.
When the dumpster passes the Nosh Ole Café, the trash can is seen on the left side of the door. After Isabella and Vivian exit the café, the trash can is seen on the right side. This happens again when Phineas is about to enter the café.
When Adyson suggests Ginger to manipulate the situation, for some reason Gretchen's left eye is not attached to her face.
When the dumpster hits the dinner setting, some decorations are still on the grass. After Baljeet asks the company to take a look at the ruined setting, the decorations are suddenly swept away.
When Vanessa pulls up in the yellow sports car, it only has two seats. When she pulls up beside Isabella's car, it has an extra third seat in the back on its own. Additionally, there are no other seats besides the one in the back.
During Mid-Life Crisis, Perry's jetpack disappears throughout the song and then reappears again after the song ends.
When Phineas comes up to Isabella's car at the end, she rolls down the window and leaves the car. When the car is in the next shot, the window is rolled up.
When Carl calls Monogram in Bora Bora, he dials only 7 numbers, but when making a call from the US to French Polynesia, you would have to dial 12 numbers (011 + 689 + local number).
Baljeet mentions the time Isabella's eyes formed hearts, which was only seen in the very first episode, "Rollercoaster". Oddly enough, he wasn't introduced yet in the said episode.
When Buford enters the house, Adyson is seen stirring in the kitchen, and she doesn't wear an apron. When Buford approaches her as the screen zooms in, Adyson suddenly wears her apron.
When Katie says that it was exactly like their childhood, Adyson's clothes are all blue instead of a blue top and skirt.
At the same time, Katie's hair moves from behind her arm in one frame to in front of it in the next.
Also, Adyson's and Gretchen's phones change color from black to white.
Baljeet with an extra mouth
When Baljeet says that he and his friends were trying to get Phineas and Isabella together, he has two mouths at one point.
When the gang finishes setting up the dinner and starts to call Isabella, Milly is missing. Also, when the Fireside Girls give farewell to Isabella, she is nowhere to be seen.
Isabella does not have any pupils
In the confession scene, Isabella's pupils briefly disappear after she says "I've been busy".
When Vanessa drives up to Ferb right after Isabella leaves, Baljeet, Buford, and the Fireside Girls suddenly disappear.
When Candace and the rest of the gang try to get Phineas and Ferb out of Nullville, it takes them a while to get sucked inside the portal, even though everything else was sucked in immediately earlier in the episode.
In the multiple scenes where Vanessa is trying to tell her dad about her O.W.C.A internship after Doofenshmirtz walked out of his bedroom, different backgrounds could be seen.
After Phineas and Ferb disappeared from existence, Candace's alarm should not have had Phineas' voice saying, "I know what we're gonna do today."
Soon after arriving in Nullville, Phineas says, "I hope no one at home is planning to baste a turkey while wearing suspenders and Capri pants." But we don't see any suspenders until later (when Ferb uses them to tie together a big bouncy ball of Capri pants), and turkeys don't appear in Nullville until even later (Buford gets buried beneath a pile of them).
During "Serious Fun":
When Phineas is singing "One last day in the sun" to Baljeet, his hair disappears briefly.
The sky color changes when they arrive at Buford's house.
Isabella's hoverboard has a jet engine, but in the other parts song, the engine is missing. In the other parts of the song, it can be seen again.
The cosine of 84.7 is not 17 as stated by Candace, but rather 0.09237 (if measured in degrees) or -0.99244 (if measured in radians). Candace may have accidentally inputted the tangent of 86.7 though, since that would give 17.34315 if measured in degrees.
In the very last scene, when Phineas closes the door after waving to the audience, it closes facing forward, not diagonal with the wall bindings.
In Nullville, Baljeet says that if they destroyed the machine while they were there, they would have no way to get out. However, all the other items that arrived there came back into time after they destroyed it, even though they did not take any of the items with them when they came back through the rift, apart from the muffin Buford squished and the spoon Candace used to throw at the machine's self-destruct button.
When Candace explains the disappearance of her brothers to the gang, as Baljeet is scanning temporal time rifts, his right arm is superimposed over his jumper.
When the gang is seen cheering after seeing oranges and spoons return, Phineas seems to open his mouth to say, "Yeah!", but nothing is heard.
When Linda says, "Which means back to school errands for me...", her left arm suddenly goes from at her side to pointing with no in between animation.
Baljeet asks who "that girl in the bathrobe" is, but Candace is wearing her pajamas, not a bathrobe.
When this episode aired on Disney XD on June 23, 2015 during the commercial breaks, the Disney XD announcer says that the audience is watching Zeke and Luther, not Phineas and Ferb. He says "We'll be right back with Zeke and Luther on Disney XD" and "Now back to Zeke and Luther on Disney XD".
Just before the boys reveal their big idea, a patch of Buford's pants below his left hand is red instead of brown.
During the final loop, Baljeet is missing.
On the Closed Captions of the episode, when Candace throws the Capri pants, Buford's "Hey!" line was entitled to Phineas.
The captions also almost completely mess up the lyrics for "Curtain Call/Time Spent Together".
During the song Time Spent Together:
At some points of the song, Adyson's headband has the same color as her hair.
Candace and Baljeet's microphone stands repeatedly disappears and then reappears again.
Some characters' mouths do not move, although their voices can be heard during certain parts of the song.
Isabella's bow is pink but when Baljeet says "Who's that girl in the bathrobe?", it turns into purple.
When Baljeet is remembering what spoons are he remembers a scene from "Mind Share". That is impossible because he was in jail.
How did Candace change in one second?
During Tomorrow is This Morning Again, Candace is in her bedroom with pajamas on. After she exits, she is wearing her normal clothes.
During "There's No One I'd Rather Go Nowhere With" there's a brief moment where Isabella's belt is the same color as her dress.
The Netflix subtitles misspell "Tri-Governor Inator" as "Tri-Govern Inator".
The copyright says 2014 instead of 2015. The same mistake was spotted in "Act Your Age", but both episodes were produced in 2014.
In the photo of Doof with the ocelots, Doof is a baby. But in "The Chronicles of Meap", the flashback of Doof with the ocelots depicts him as already being an adolescent.
"Last Day of Summer" may have led up to this plot after Vanessa said she was getting an internship at OWCA and they were looking for a few good animals, which made Dr. Doofenshmirtz want to join since he was raised by ocelots. However, The OWCA Files completely ignores that Vanessa became an intern and she is not seen or mentioned.
Supposedly only full agents have black hatbands and trainees wear yellow ones, but in "Agent Doof" Doofenshmirtz wore the full black hatband while only a probationary agent. However, this rule may have been made after Agent Doof.
When Parenthesis tells the 2 plumber fleas to fix the pipe, both of their mouths were dark grey, but when they were seen fixing the pipe, one of their mouths turn the same color as their body.
During the time when Carl and Monogram were sneaking around, Carl's eye cornea turns blue in their sneaking moves.
When Carl shows the photo of Doofenshmirtz with the ocelots, the ocelots' eye corneas are black when they should've been white.
When Karen destroys the mecha-fleas in the training carnival, the trashed fleas' eye corneas were black.
During the time all of the Agents go back to normal, Agent D's ears were the same color as his body fur instead of dark brown.
Tiny crumbs of the Bug Trio have been seen coming out of the fan after Napoleon said that they would've ended up just like the peanut, but after they free themselves from the fan, they were completely unharmed, this also happens after they print themselves.
After the flea extermination two of the gas masks' glass lenses are missing.
At the same time, Agent Bear's gas mask was missing it's lenses as well, they reappear for a split second than disappear again.
When Parenthesis attacks Monogram and Carl in the OWCA building, Agent Pig's eye pupils were missing.
At the same time, the black spots surrounding Peter's eyes were red and his eye pupils were missing. The eye pupils should've been visible and red.
At the end of the song "Bits of All of Us", when Harry breaks the guitar, after he smashes it against a wall, the black part of the guitar disappears, unless the guitar rapidly flipped over.
When the Agents were trapped by Parenthesis in his lair, there was a wrecking ball, at some points, the wrecking ball disappears.
At the same time, the torch moves to a different spot.
When Carl and Monogram prepare to sneak around the animals, when they see the giant teddy bear, it's eyes were black, but when they prepared it, the bear then had no eyes unless they were taken out by Carl or Monogram.
When Carl and Monogram prepare the teddy bear, the teddy bear had no eye corneas, but during the song "Friend Like Mine", the teddy bear did have eye corneas.
At the same time, Monogram appears to be too tall for Carl to fit inside the teddy bear, unless Carl squatted.
When Parenthesis and the mecha-fleas step in the OWCA building, the fleas had no capes or fangs, but when Carl and Monogram get grabbed by the fleas, the fleas did have fangs and capes.
When Parenthesis's lair explodes, fire was on the whole top of the lair, but when it comes down on the Agents, the flame are only on the front. The other flames may have however burned out.
When the Bug Trio are being photocopied, the image displays like an x-ray, showing their pelvises, spinal cords, and ribs. However, as insects, they should have exoskeletons instead of internal bones.
In the credits, John Kranjcevich's surname is misspelled as "Krancjevich".
