Since it's our last day of summer, we're thinking a grand finale is in order!

— Phineas Flynn

On the inevitable 104th day of summer vacation, the season — and the series — is quickly coming to an end and it’s Candace’s last chance to bust her brothers; who build huge playground equipment for the finale of summer. She is quickly foiled, but when she goes to return a DVD to Vanessa and finds Dr. Doofenshmirtz’s Do-Over-Inator, she finds an opportunity to redo the day, which results in other consequences like rips in the space-time continuum, the shortening of days and the disappearance of her brothers.

Episode Summary

Act I

Last Day of Summer - PeF001 - Image 16

We got one last day of summer, let's have some serious fun.

On the morning of the 104th day of summer vacation, Phineas and Ferb invite the rest of the gang on a hoverboard ride across Danville.

Candace wakes up just in time to hear her brother say his catch phrase and shouts to the gang that she intends to bust them once and for all. Candace is especially determined to bust them since this is the final day of summer vacation, but she trips on a roller skate, and a skateboard, and rolls down the stairs and lands into a wagon. Linda and Lawrence read the newspaper about a new tiger habitat at the Danville Zoo. Candace wheels into the dining room to hear that Linda has to do some errands to get ready for school resuming the following day.

Candace falling down the stairs

Candace is starting the day on the wrong foot.

In the backyard, Phineas and the gang determine to do something big since they have one more chance to find a good way to spend summer vacation. Phineas shows the gang a massive blueprint. Buford then wonders where Perry is.

Agent P enters his lair the very same way he entered it on the first day of summer. He enters his lair to discover that Carl already left for college, so Major Monogram has to do his own inserts manually. Monogram tells Agent P that he suspects Doofenshmirtz will do one last big evil scheme to take over the Tri-State Area. The manual inserts come apart and Monogram lashes out at Carl, only to remember that he's already heading for school. As Monogram mopes over Carl's absence, Agent P goes straight to his mission.

Act II

At Doofenshmirtz Evil Incorporated, Doof wakes up in his bed but hits his head on the lamp, which he disintegrates. Norm comes in to give him some chocolate cake for breakfast, much to his annoyance. He gets out of bed to see Vanessa coming to talk to him, but Doof does not have the time since he has a big to-do list, so Vanessa leaves him alone.

First incarnation of the last big idea

This final invention has everything! Kitchen sink included!

Back in the backyard, Phineas reveals the big idea, a giant, enormous tribute to every single thing they did over the summer. Buford wonders if it really is worthy of a grand finale. Phineas suggests they make sure that they hit the mark. Buford at first suggests they focus test it, but Phineas suggests they ride it. The gang rides on the contraption, which encompasses various fun and surreal things. Candace walks out and calls her mom. Baljeet reveals the reaction to the ride is almost unanimous, but Buford suggests some improvements. Phineas decides to go back to the drawing board, so Ferb transforms the ride into a drawing board. Candace and Linda come into the yard just in time to see nothing there and for Candace to once again "but but but". Candace decides to return some DVDs she borrowed from Vanessa.

Doof, Candace, and the Do-Over-inator

Doof explains the Do-Over-inator to Candace.

Agent P arrives at DEI and immediately gets trapped in the bass drum of Norm's drumset. Doofenshmirtz explains to his nemesis that he realized that his goal of ruling the Tri-State Area was all for naught since it turned out there was no such position. So he unveils his newest inator, the Tri-Governor-inator, which will make him "Tri-Governor", a term he made up to mean the Ruler of the Tri-State Area. Perry escapes from his trap and fights Doofenshmirtz, but then the doorbell rings. Vanessa answers it to see Candace at the door. Upon seeing this, Perry runs and hides, as he doesn't want his cover to be blown. Candace returns the DVDs and vents to her about her failed busting attempt. Candace walks into the lair while Vanessa gets some tea. Candace then talks to Doof about her failure to bust her brothers, but Doof does not listen since he is looking for his nemesis. Candace then sits on one of Doof's inators, which he gets her off of. Doof explains that it is the Do-Over-inator, which is able to do the day over again through a time loop. Candace is intrigued by this and believes that she might have a chance of busting her brothers. Without hesistatation, Candace activates the -inator, and a bubble appears surrounding herself and Doofenshmirtz.

Suddenly, Candace finds herself back in her bed waking up to her alarm clock. When Phineas tells her that it is the last day of summer, Candace is elated to have one more chance to bust her brothers, but, once again, she slips and falls down the stairs. She finds herself reciting along with her parents, but they laugh it off as a philosophical thing.

Meanwhile, Doof also finds himself back in his own bed, confused why the lamp is back and Norm is once again offering him chocolate cake for breakfast. When he gets out of bed and sees Vanessa in the hallway again, he realizes the Do-Over-inator worked and he has a chance to improve his traps. But Vanessa is aggravated that her father is not listening and tells him she is permanently moving to her mother's.

You're BUSTED (BUS—Wait, wrong song.

Upon hearing of Vanessa's last words being recorded by Norm, Doofenshmirtz jumps to the conclusion that Vanessa is moving out simply because she thinks he is a loser. He figures that if he finally becomes the Tri-Governor, he can get Vanessa to move in with him. Both Candace and Doof celebrate the awesome power of the Do-Over-inator.

Candace walks into the backyard when the gang reveal the blueprints and tells them this time that she will get her mom instead of calling her. After hearing Candace refer to the invention as "sky-high", Phineas gets an idea on how to improve it.

Perry gets trapped in the bass drum again, only this time, he rolls past Norm's drum set, escapes, and gets trapped in a giant skull. Perry escapes that trap as well and immediately hits the self-destruct button on the Tri-Governor-inator. Despite this, Doof states that as long as the Do-Over-Inator is activated, he will still find a way to defeat Perry.

Candace once again brings her mom to the backyard, only to discover once again there is truly nothing there. Once she leaves, it is revealed that Phineas and the gang decided to levitate the invention.

Candace wakes up from her bed a third time and realizes the day is once again repeating itself. This time, she attempts to avoid the roller skate, but still manages to slip onto a third roller skate and once again fall down the stairs. This time, Candace practically pushes her mom out the door.

Doofenshmirtz once again wakes up, but this time, he avoids the lamp. He tells Norm to "stuff it", so Norm eats the cake himself. Vanessa once again tries to talk to her father, but he too busy once again making improvements to his traps.

Doof and Perry both trapped

Doof keeps trying to make improvements on his traps.

After Perry gets trapped in and escapes the skull, he gets trapped in a metal box, and Doofenshmirtz encases himself in a giant hamster ball. Perry escapes the trap and rolls Doofenshmirtz around the room. Norm offers some muffins, but they suddenly disappear into thin air.

Time rift takes away Lawrence's spoon

A time rift makes spoons disappear from existence.

Candace once again wakes up, and this time avoids all the things with wheels and once again pushes her mom out the door. As soon as she leaves, the spoon that Lawrence was eating cereal with disappears just like the muffins. Lawrence shrugs it off and laps at his cereal like a dog.

When Candace enters the backyard, she tells the gang she is going to bust them "out of this world", which brings further inspiration. During a montage, we see the various other ways both Candace fails to bust her brothers and Doof fails to trap Perry, each one weirder than the last.

Doofenshmirtz Tri-Governor's Mansion

Doofenshmirtz Tri-Governor's Mansion.

After 23 loops, Doofenshmirtz ensures that he finally perfected his trap. He asks Norm for some muffins, but Norm is confused because he does not know what a muffin is, which made Doof realize that the effects of the Do-Over-inator creating time rifts in the space-time continuum that can erase anything from existence. After Perry is finally trapped (off-screen), Doof fires his inator at City Hall, which replaces the dome with a Tri-Governor's Mansion, much to his delight. He then proceeds to put up a voting booth to get the citizens to vote for him for the upcoming election.

Candace once again walks into the kitchen but then notices her parents both lapping at their cereals. She discovers that they do not know what a spoon is nor what tigers are. Things get even stranger when she notices her mother wearing green cargo shorts in place of her normal Capri pants. Candace then starts to suspect that something is going very wrong.

Meanwhile, Doofenshmirtz talks to Vanessa about her intent to move out and shows her the news about the election. His younger brother Mayor Roger is about to publicly announce the final results, only to find out in horror that Doof has gained enough votes to win. A victorious Doof assumes that his daughter will want to live with him now that he has finally succeeded in his goal, but Vanessa isn't impressed by this. She tries to tell that what he assumes isn't the case, but she is interrupted again when Doof tells her to pack up her things as he runs off to turn off the Do-Over-inator to ensure that there won't be any more loops. However, a time rift sucks up the Do-Over-inator, so Doof assumes that since the machine is already erased from existence, there will be no more loops. He proceeds to move in to the Tri-Governor's Mansion with an unimpressed Vanessa.

Phineas and Ferb disappear

Candace watches as her brothers disappear from existence.

Candace runs to the backyard and asks her brothers to help her. She explains that she activated the -inator and days are repeating and things are disappearing. However, another rift appears and suck her brothers, much to Candace's dismay. She goes to her mom to tell her what happened, but Linda is confused because she has not heard of anyone named "Phineas" or "Ferb".

Act IV

Horrified to see that her mother doesn't even remember having two sons, Candace tries to explain the situation to Linda, but the latter is still very confused, much to Candace's complete frustration.

Meanwhile, in the Tri-Governor's Mansion, Doofenshmirtz proudly shows Vanessa her own First Daughter suite. Though Vanessa somewhat admires the new features of the suite, she tries to tell her father the true reason why she's moving out. However, Melanie comes in to tell Doof that he has a lot of things to do as the new Tri-Governor since his work schedule is crowded, much to Vanessa's dismay.

Phineas and Ferb in Nulville

Phineas and Ferb wandering around a colorless void.

In a rather gray and colorless void that resembles Danville, Phineas and Ferb are wandering around and taking in their surroundings. They suddenly discover the things that disappeared including spoons and Capri pants. They then see oranges coming down from the sky and hear something roaring in the distance, presumably tigers.

Candace goes to Isabella's backyard to see that the gang still know each other, but can't stand each other. Buford and Baljeet have no idea who Candace is and Isabella thinks she is an only child. Candace then tries to explain the situation to the gang, but they are unperturbed by this.


Doofenshmirtz has finally taken over the Tri-State Area and Perry is forced to accept defeat.

In his new office, Doofenshmirtz awaits the arrival of a furious Perry (who has inexplicably escaped from his unknown trap, but was too late to foil Doof's scheme). Doof reveals that he has put up a law that declares it illegal for Perry and the rest of O.W.C.A. to thwart the Tri-Governor until his term is over, and that it's been declared legal. Doof then presents out the legislation paper to Perry to prove that he isn't bluffing. Realizing that he can no longer thwart Doof anymore, a depressed Perry is forced to concede defeat and leave the mansion in shame. Doof also proclaims that he will send Perry a bill for burning the carpet with his jet-pack. Roger then contacts Doof through the intercom, berating him for having Melanie to work for him, but Doof taunts him back by saying that he's the boss of him. After being given a stack of more legislation papers to sign, Doof notices another time rift sucking up his snow-globe and orders Melanie to bring in another one, only to find out in horror that Melanie doesn't even know what a snow-globe is. He then realizes that even with the Do-Over-inator gone, the time rifts are still erasing a lot of things from existence.

Back in the void, Phineas and Ferb collect all of the things that dropped into it. Suddenly, they see the tigers and then snowglobes falling from the sky. They run away from the impending danger.

Candace "Eh? Eh? Eh?"

Candace attempts to convince the gang to help her.

Candace is still trying to convince the gang that she had two brothers and that they are friends with them. Using his contraption, Baljeet then notices some fluctuations in the space-time continuum and explains about the risks that the time rifts are causing that will erase anything from existence. Candace attempts to use this to prove her point to Buford and Isabella, but they are still not convinced.

Meanwhile, outside the Tri-Governor's Mansion, Monogram informs a miserable Perry about Doof's anti-thwarting legislation, confirming that it is legitimate and that they can no longer touch Doof anymore. Monogram regretfully adds that as a result of this occasion, Perry is temporarily suspended from work until Doof's term is up. Vanessa sees Perry moping over his failure and reveals her true reason why she's moving: she was accepted into O.W.C.A.'s internship program, but that she can't join it if she's living with her father (who happens to be one of O.W.C.A.'s wanted enemies). Vanessa then decides to tell him and convince him to let her do things her way, and Perry wishes her luck.

Back in Isabella's backyard, Baljeet is giving further explanations of the rifts in the space-time continuum. Only Candace is intrigued as she is aware of the effects, but Isabella and Buford are still not convinced as they are bored out of their minds.

Meanwhile, Phineas and Ferb decide to distract the tigers by giving them a giant ball of yarn made of all the suspenders and Capri pants. The plan works, and both boys run off, still planning on how to get home.

Vanessa tells her father he's not evil

Vanessa helps her father realize that despite his newfound success as Tri-Governor, he is terrible at being an "evil" scientist.

After finishing up his work schedule as Tri-Governor, Doof returns to Vanessa's suite, where Vanessa finally tells him about the internship and that she still has to move out. Doof is completely shocked by this, but Vanessa states that the only reason he builds his -inators is simply to prove that he is evil, but that he only acts evil only as an obligation to his miserable childhood, not from what's coming from his heart. She also confesses that the internship is something she really wants to do and asks her father if he's really happy with his new job as Tri-Governor. Doofenshmirtz then realizes that despite his newfound success as Tri-Governor, he is actually unhappy in ruling the Tri-State Area. Vanessa then suggests to her father to turn over a new leaf and become a good guy.

Before Doof could do anything, the loop starts over again, and Doof and Candace find themselves back in their beds, much to their distraught. However, finally aware of Vanessa's true intentions, Doofenshmirtz tells Vanessa that he knows all about the internship and that he is turning over a new leaf for her sake. Vanessa is a little freaked out by this, but satisfied. Finally deciding that he needs to stop the time loops, Doof tells his daughter he plans to build one more -inator, the Time-Straighten-Out-inator, which will help straighten the space-time continuum.

Candace brings the very sleepy and grumpy Isabella and Buford to the equally sleepy Baljeet's house. Once again, Baljeet and Buford have no idea who Candace is, and still cannot stand each other. Candace gets the device Baljeet was measuring the space-time continuum with and gives it to him. Baljeet is horrified to see how unstable it is. Candace once again tells them the situation of her missing brothers. Baljeet suggests that they can find the location of the next rift and throw a rope and life preserver into it to rescue them.

As Doof and his daughter begin to build the -inator, Doof explains to Vanessa about the Do-Over-inator's effects, and that he and Candace are the only ones to notice the effects because they were inside the bubble when it was first activated. Right on Doof's cue, Perry comes in expecting a trap, but Doof tells him he turned over a new leaf and needs his help. Perry, not really believing his frenemy, reluctantly provides his assistance.

Candace and the gang about to rescue Phineas and Ferb

Candace and the gang await the next time rip to appear so they can rescue Phineas and Ferb.

After a few last-minute calculations, Baljeet discovers the next tear in the fabric, and it sucks up a groundhog. Meanwhile, Phineas and Ferb do some calculations of their own to try to find their way out, but the groundhogs mess up their calculations. In Danville Park, Baljeet finds the location of another anomaly. Candace throws the life preserver into it and calls out to her brothers to grab it, but the rope pulls Candace and the gang into the void.

Act V

Doof, Vanessa and Perry finish building the inator, but another loop begins before they can activate it.


The gang survey their surroundings.

Candace, Buford, Baljeet, and Isabella fall into the void and are greeted by the strange triangle-headed boy and the quiet green-haired guy next to him. Isabella suddenly looks at the triangle-headed boy and all the memories of her secret crush come back to her. Baljeet has a similar experience with spoons as does Buford with oranges. Candace is so overjoyed to see her brothers again. Baljeet believes that the void they are in exists outside the flow of time and Candace reveals to him that the days were getting shorter. This worries Baljeet because as the time pocket disappears from existence, everything else in the void will also cease to exist, including the entire gang.

Doof once again meets his daughter and once again begins building the Time-Straighten-Out-inator. Perry comes in to help once again as well.

The Buford van Stomm Time Catapult

The time catapult built by the gang to get them out of the void.

Baljeet demonstrates the cause and effect of the shrinking of the space-time continuum with a paper towel and a hook. He then begins to wonder how Candace was unaffected by this and how she knew. Candace just nervously looks at the others and tells them not to question it. Baljeet then tells them that something has to be built to stop the looping once and for all. Buford then sees the Do-Over-inator, but Candace inadvertently reveals what it is. She finally confesses to the gang she was the one who pushed the button because she was so eager to bust her brothers. Buford suggests pushing the self-destruct button to negate the effects, but Baljeet warns that if they push it in the void, they will be no more time rifts to travel through, meaning that they will be unable to go back to Danville and be forgotten forever. He suggests finding a way to get both themselves and the inator through one of the rifts back to Danville so that they can push the button and destroy the machine. As such, Phineas and the gang get to work building a catapult. The gang gets into the catapult and Baljeet makes a calculation of multiple rifts coming. The rifts appear and cars begin to fall out of the sky. After Baljeet gives the coordinates, and Phineas adjusts the catapult, they launch themselves toward the rift, which appears in the nick of time and sucks them in.

Act VI

Doof explains the risks involved

Doof rambles on about the risks of the Time-Straighten-Out-inator.

Doofenshmirtz, Vanessa and Perry finish the inator faster than before. Doof tells the others the 55% of chance will lead to success, but Vanessa wonders what the 45% entails. Her father explains that 45% might bring about wiping everything from existence.

The gang make their return to the backyard, but the inator lands on the far side of the fence. Candace and the others run up to the inator. Phineas asks for a confirmation from Baljeet that destroying the inator will put everything back to normal. Baljeet confirms this and says they need to do it quickly since the time loops are getting shorter.

Suddenly, the time loop begins at the point where Doof and the others finished the inator. Doof once again gives the percentages. He assures Vanessa it is only a worst-case scenario. Vanessa then wonders what happens if they don't push, to which her father explains that if that happens the time pocket will be destroyed, but rambles too long.

The gang crash land in the backyard

Phineas and the gang make it back in time.

Meanwhile, Phineas and the gang's time loop begins at the point where they returned to the backyard. They once again attempt to run up to the inator, but their time loop isn't long enough.

Once again, Doof recaps all three of the percentages. He then asks Perry if he has any concerns, but before he can make the digga-digga-digga sound, the time loop ends again.

Phineas and the gang land in the backyard again. Candace then sees a spoon tucked into her skirt and gets an idea.

Doof shortens his spiel to saying that there is a lot of risk involved, but ensures the others this is their only option. Vanessa and Perry assure him they are with him.

Candace throws the spoon at the self-destruct button, and Doof pushes the button on the inator. Both Candace and Doof spin around in a blue vortex, thereby successfully ending the loops and bringing everything back to normal. This is confirmed when Linda comes out offering orange juice, which Lawrence squeezed with a spoon.

Meanwhile, Doof gets reassurance that everything is back to normal when Norm comes in with muffins. Doof then wonders what he'll do next, since he is not good at being a good guy. Vanessa then tells him that OWCA is looking for some new recruits. Perry then discovers the inator was not plugged in, wondering what could've stopped the loops.


It's been a great summer and we thank you for comin’ along!

In the backyard, Phineas, Candace and the gang are enjoying their orange juice and sharing their favorite memories of their summer. They continue to bond and reminisce. At one point, Phineas and Ferb fist bump each other. Even Candace gives Phineas a noogie and laughs along with the gang. Meanwhile, Perry, Doof, Vanessa and Norm do some reminiscing of their own while enjoying some muffins.

After a camera pan up to the summer sun, the backyard becomes a concert stage where all of the main characters, with some backup from the Fireside Girls, sing and dance about their awesome summer and bid all their fans and viewers, “Thank you for comin’ along!”

  • When Candace brings Linda home during the first do-over, the Big Idea was floating over them, but somehow they both did not see the shadow of the playground.
  • When Candace and the rest of the gang try to get Phineas and Ferb out of the city, 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 was 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.
  • During the song "Serious Fun" Isabella's hoverboard has a jet engine, but in the other parts song, the engine was missing. In the other parts of the song, it can be seen again.
  • The cosine of 81.7 is not 17 as stated by Candace, but rather .144 (if measured in degrees) or .999 (if measured in radians).
  • 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 said 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 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 there big idea a patch of Buford's pants below his left hand is red instead of brown.
  • 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".
  • 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.
  • 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 copyright says 2014 instead of 2015. The same mistake was spotted in Act Your Age.

    How did Candace change in one second?



  • Groundhog Day - Candace waking up to her alarm and realizing that she's reliving the same day is very similar to Phil Conners (Bill Murray) waking up to "I Got You Babe" and realizing he's living the same day in this film. Also, the groundhogs getting sucked into the anomaly is a wink to the movie, specially the moment when Phineas says: "I hope this doesn't mean 6 more weeks in nullville".
  • A Christmas Carol - Candace says to Phineas, "You there, boy, what day is it?" in reference to what Ebenezer Scrooge asks in the ending of this Dickens novella.
  • Bill Cosby - Norm feeds Doofenshmirtz chocolate cake for breakfast. Bill Cosby did a standup comedy routine involving having cake for breakfast.
  • The Muffin Man - Doof sings this traditional nursery rhyme.
  • The Langoliers - In an interview with, Dan and Swampy say this episode was inspired by this Stephen King novel. However, contrary to Dan's statement, the novel was not written by King as Richard Bachman.
  • Seinfeld - Doofenshmirtz greets his brother by saying, "Hellooooooo, Roger", which is how Jerry greeted Newman. Incidentally, John O'Hurley, Roger's voice actor, portrayed the recurring role of Mr. Peterman in the final years of the show. This could also be an alusion to the own Phineas and Ferb show due to the fact that everytime Roger sees Heinz he says: "hello Heinz".
  • Doctor Who (series 5) - Holes in space-time eat people and things, causing everybody else to forget about them, and only the tall red-head remembers. Additionally, the time loop animation that restarts each day is a clear reference to the 12th Doctor's title sequence used in Series 8 and 9.
  • The Jeffersons - Doofenshmirtz tells Vanessa that they're "Movin' on up.", which is a line from the show's theme song.
  • George Washington - In one part of the boys' big idea you can see the story of George Washington chopping down a cherry tree.
  • U.S. Marines Corp - Vanessa tells her father that OWCA is "looking for a few good animals". This is a reference to the Marines' advertising slogan, "We're looking for a few good men". The phrase was further popularized by the 1992 film A Few Good Men.
  • Back To The Future II - Phineas and the gang's hoverboard are similar to Martin McFly's hoverboard in that movie.
  • The Twilight Zone - People and objects disappearing from not only existence but from other people's memories is nearly identical to The Twilight Zone episode "And When The Sky Was Opened"


  • This premiered at the end of the Phineas and Ferb Last Days of Summer Marathon.
  • Sixth and penultimate hour-long episode. ("Phineas and Ferb Summer Belongs to You!", "Phineas and Ferb: Mission Marvel", "Phineas and Ferb Save Summer", "Phineas and Ferb: Star Wars", "Night of the Living Pharmacists") Surprisingly, the latter four all premiered throughout the fourth season.
  • During the opening song's lyrics "We're doing something and it's gonna be big" the boys quickly show a blue print that compares sizes of major structures: The Great Pyramid, The Gateway Arch, The Space Needle, The Eiffel Tower, Doofenshmirtz Evil Inc., The Empire State, The CN Tower, and a large question mark.
  • Isabella's hoverboard is the only one with a jet engine.
  • During much of the series, Vanessa believed that her father was evil and tried to tell her mother Charlene about it, only for Charlene to dismiss it. ("I Scream, You Scream", "Hail Doofania!") However, in this special, Vanessa finally comes to the fact that Doof isn't as evil as she may previously thought him to be.
  • Second time Perry plays a guitar. ("The Lizard Whisperer")
  • Third time where the top flat part of Isabella's head could be seen. ("Wizard of Odd", "Summer Belongs to You")
  • Third time Doofenshmirtz sings with Phineas and Ferb's friends. ("Phineas and Ferb Interrupted", "A Phineas and Ferb Family Christmas")
  • Fourth episode involving time travel. ("It's About Time!", "Phineas and Ferb's Quantum Boogaloo", "She's the Mayor")
  • Candace and Vanessa interact again ("S'Winter", "Phineas and Ferb Summer Belongs to You!", "The Doonkelberry Imperative", "It's No Picnic", "Night of the Living Pharmacists")
  • Second special episode when Vanessa gets mad at Doof ("Phineas and Ferb Summer Belongs to You")
  • Fourth time Candace and Doof interact. ("Fireside Girl Jamboree", Phineas and Ferb The Movie: Across the 2nd Dimension, "Night of the Living Pharmacists") First time they sing together. Their song has some similar movements to "Busted", except Doofenshmirtz takes place of Vanessa.
  • The episode starts in a similar way to "Phineas and Ferb: Mission Marvel".
  • Someone gives the "I'm watching you" gesture again. ("One Good Turn", "Wizard of Odd")
  • This is the second (and final) time Doofenshmirtz had succeeded in taking over the Tri-State Area, since he managed to build the Tri-State Governor's Mansion in Danville and had himself elected as the first Tri-Governor. The first time was in "Phineas and Ferb Save Summer", when he moved the Earth away to an early autumn, which allowed him and his fellow members of L.O.V.E.M.U.F.F.I.N. to take over City Hall after it caused civil unrest.
  • The second hourlong episode where Stacy doesn't appear ("Phineas and Ferb: Star Wars").
  • Fourth time Doofenshmirtz mentions having been raised by ocelots. ("The Chronicles of Meap", "Phineas and Ferb The Movie: Across the 2nd Dimension", "This Is Your Backstory")
  • Second episode with "Last" in the title ("Last Train to Bustville").
  • Third time Candace uses the phrase "once and for all" ("Picture This", "Wizard of Odd").
  • When Isabella is regaining her memory upon seeing Phineas, the music played is the same as when they kissed each other in "Act Your Age".
  • Second time Norm says, "It's muffin time, sir." (AT2D)
  • First time the "Platypus Walk" lyrics are heard on the series.
  • Fourth time the word "Doppelgänger" is said. ("I, Brobot", "Cheer Up Candace", "Make Play")
  • During the ending song, Candace did the imitation of Klimpaloon which was seen in "The Klimpaloon Ultimatum".
  • Some of the things that fall into the void are cans of almond brittle, which is frequently cited as Doof's favorite delicacy.
  • Third time the day is saved by throwing a small object at a target. ("Meapless in Seattle", "Phineas and Ferb: Star Wars") Second time Candace is the one who does so. ("Meapless in Seattle")
  • Doof mentioned being raised by Ocelots again ("The Chronicles of Meap", "Skiddley Whiffers", "Agent Doof", "It's No Picnic".)
  • During the montage of do-overs, in the fourth one Candace is wearing the clown costume from "Cheer Up Candace".
  • During Curtain Call/Time Spent Together, many of the characters are exposed to things that they're not supposed to ever see in the series. Linda comes out at the end, asking the kids if they want some pie, clearly being able to see everybody standing on top of the giant stage, but she doesn't even acknowledge its existence, nor does anyone else. Phineas, Ferb, and Candace also must be aware of the fact that Perry is a secret agent, as he is seen on stage with them, in secret agent form, and they don't even acknowledge that either. However, given the fact that everybody made references to multiple events that they either wouldn't remember or didn't happen during the summer, and the fact that in the shot where they were getting off the podiums, Doofenshmirtz, Major Monogram, and Carl were all seen walking to the house, but then in the shot where everyone went into the house, only the people who were actually there in the episode were seen, it can be said that this entire scene with them singing on stage was non-canon.
    • This scene is similar to the song Carpe Diem, where Perry was seen dancing as a secret agent on the stage, when the Flynn-Fletcher family was around and how Linda was seen on stage, aware of the stage Phineas and Ferb built, yet no one even acknowledged that it was happening.
  • It is unknown whether 104 days is eight years in real time, if time never passes in Phineas and Ferb, or if the 223 episodes take place over 104 days.
