|“||With a minimal amount of research, Ferb's found out that The Lost City of Atlantis is probably located right off the coast of Danville.||”|
— Phineas Flynn
During a trip to the beach, Phineas, Ferb, Isabella, Buford, Baljeet and Irving try to find the lost city of Atlantis which is located in the bottom of the ocean. Then Candace and Linda enter a sandcastle building contest when Candace found out that Jeremy is the judge. Meanwhile, Doofenshmirtz creates an army of plants.
Candace is looking for some peace and quiet on the beach. Unfortunately, Phineas, Ferb, Isabella, Buford, Baljeet and Irving are with her and Linda. Isabella asks everybody if anyone wants to play volleyball with her. Linda points out to Candace that there is a sandcastle contest on the other side of the beach. Linda tells Candace to join up but she replies saying that Phineas and Ferb would build a skyscraper or something huge so it wouldn't be worth to compete. Phineas joins in the conversation saying that they'll be finding Atlantis, which was probably off the coast of Danville. Isabella and Buford agree with the idea and Irving comments how he was lucky to be with them.
Perry walks up to a man playing a guitar (a variation of Perry's theme tune) and Perry jumps into the man's guitar case. He falls into his chair where Carl greets him, wearing a mustache and pretending to be Major Monogram. Carl tells Perry half of his mission when the actual Major Monogram appears and takes over the briefing. He concludes the briefing and Perry flies off to Heinz Doofenshmirtz's blimp.
The kids are in scuba diving gear and Phineas tells Linda that they're going to find Atlantis. Linda says that they have such active imaginations. Candace realizes that the group leaving the beach means they won't participate in the sandcastle competition. Candace grabs Linda and tells her they will be entering the competition after all. Shortly they both start building a sandcastle.
The group is underwater when they start to find some lost artifacts, such as the Titanic, Amelia Earhart's wrecked plane, and the tomb of Poseidon. Phineas tells the group to focus on finding Atlantis and Ferb's GPS gives the group directions. Baljeet then asks Buford why the water is always warm around him which Buford simply returns a glance at him. Back at the beach Candace orders Linda what they need to do in order to build a successful castle.
Meanwhile, Doofenshmirtz is in his blimp watering the plants he bought when quietly Perry climbs through the window and lands in a sack labeled Fertilizer. Doofenshmirtz continues to water the plants whilst telling Perry what he is about to do. He has invented a growth formula to make the plants evil and help him take over the Tri-State Area.
As the group gets closer to Atlantis Irving decides to take photos. Once he has finished taking a picture, an eel steals his camera. Irving complains but Phineas tells him to use his other camera; his mind. Irving tries it whilst Isabella finds a seahorse. Baljeet says she can now earn the Underwater Equestrian Patch and Isabella says that she was being sarcastic; seahorses aren't big enough to ride. Buford then scoops a bunch of seahorses and says he is able to ride them. Phineas finds a door with ancient inscriptions telling him how to open the door. He starts to read it when Buford decides it would be easier to punch the door. A huge rock separates, showing the lost city of Atlantis. The group explore Atlantis whilst singing a song about it. Once they have finished exploring, Irving decides to take a picture of the group in Atlantis in his mind and Buford comments how he took the picture thing to a new level. Phineas suggests bringing Atlantis above the water for everyone to see.
Back on the beach, Linda and Candace are still trying to make a sandcastle but they fail for the third time. Candace grows impatient and mentions how good she used to be building sandcastles. Linda replies to Candace just to relax and have fun when Jeremy walks over and sees Candace and Linda and explains he's the judge. He then says he can't wait to see the Flynn-Fletcher sandcastle. After he leaves Candace renews her effort to finish the sandcastle and further orders Linda around.
Meanwhile in the blimp, Doofenshmirtz finishes spraying the plants with something that appears to be smoke. The plants come to life and start growing and turning evil. Doofenshmirtz's plan to attack Perry backfires on him badly with the plants attacking both him and Perry.
Back in Atlantis a delivery guy drops an order and asks Phineas if he isn't too young to be discovering Atlantis to which Phineas replies yes they are. The delivery guy commends them and takes off in his van. Then Phineas tells the group to start working.
After that we see that Doofenshmirtz is almost covered by the vines of the evil plants he created and asks Perry for help, to which Perry frees himself and jumps off the blimp leaving Doofenshmirtz alone.
Candace and Linda start working very hard to get a good sandcastle but most of it collapses, again. Jeremy walks over and starts to judge their sandcastle when Atlantis floats up. It is being lifted by four weather balloons attached earlier by Phineas, Ferb, and friends. Candace is explaining about how their castle isn't perfect but how they enjoyed making it when Jeremy sees Atlantis, believing to be Candace's sandcastle and decides to award them the first prize. He says he is going to get their blue ribbon and walks away. Linda tells Candace it must have been the way he feels for Candace that he gave them the blue ribbon.
Back with Doofenshmirtz, the plants take over most of the blimp. Perry returns a few seconds later with a chainsaw and starts cutting all of the plants and freeing Doofenshmirtz. The spiked plants thrown overboard hit the balloons that support Atlantis and causes Atlantis to sink again. Atlantis sinks before Candace and Linda see it as they think Jeremy meant their half-collapsed castle.

Doofenshmirtz is saved Perry takes off and as about Doofenshmirtz is about to thank Perry for saving him he starts to have an allergic reaction causing him to curse his immune system. Phineas and the group start to wonder what happened to Atlantis and why it didn't stay afloat. Ferb suggests that the lost city of Atlantis wanted to stay lost. Irving comments while taking pictures from his mind he forgot to take off his thumb from the "lens" and all he remembered now was his thumb.

(Line in song)
Ferb: ♪ In the waterlogg-ed city of Atlantis! ♪
Baljeet: What happened?

Oh, there you are, Perry
Perry's entrance to his lair
Perry jumps inside a guitar case.
An instrumental version of the Doofenshmirtz Evil Incorporated jingle is played as Perry approaches Doofenshmirtz's blimp.
Carl: (imitating Major Monogram) Ah, Agent P. Dr. Doofenshmirtz has been buying up seedlings for the past few weeks, and now he's up and about in his blimp. This could be--
Major Monogram: (clearing throat) Carl?
Doofenshmirtz: Oh, Perry the Platypus. You landed in my fertilizer trap. Look at you. You've "potting soiled" yourself.
Baljeet to Buford: Why is the water always so warm next to you?
Baljeet: You can get your Underwater Equestrian Patch!
Phineas: Look at this! It's a doorway with ancient runes telling us how to open it.
Buford: Forget that! Step aside!
Baljeet: We are so privileged to be in this strange and beautiful place. To think that the greatest minds in history have been searching for Atlantis for thousands of years.
Buford: Those guys are punks.
Doofenshmirtz: You see, Perry the Platypus? Your efforts to stop me have been fruitless. Fruitless? You like that? That's a good one. Next time you'll "leaf" me alone! Yes, Perry the Platypus, I sure can be a fun(g) guy. Get it? Fungi? Plural of fungus? Eheheh... Yeah...

- When everyone is at the beach, the ball that the girl and the boy are tossing to each other disappears when it leaves their hands and reappears when they catch it.
- The Titanic is shown to have its mast upright along with the steam poles and in one piece, but the mast should be lying on the bridge of the ship, the stern should be disconnected, and the smokestacks shouldn't be connected to the ship at all. Also, Titanic is shown intact in one piece, while in actuality she is broken in two. Only the ship's hull is correct as it's unpainted as the water has washed the paint away.
- The boys would have to go way deeper in the water than that to find the Titanic and the other underwater objects, including Atlantis.
- When Carl removes the fake mustache, his eye lids turn to the color of his skin. Normally, they are the same color of his glasses lens.
- At the beginning, when Baljeet complains that Buford drank all the sunscreen, immediately after, Linda is seen putting sunscreen on. She could have brought a spare one.
- The Titanic and Amelia Earhart's plane are in two different oceans.
- When Isabella says "Who wants to play volleyball?" her mouth doesn't move when she says the word "volleyball".
- Danville is surrounded by a moat (as shown in "Interview With a Platypus") but it is connected to the beach.
- Baljeet mentions the Tomb of Poseidon, even though all Greek gods are immortal.
- When Irving was "taking photos", we don't see his thumb in front of the "lens" but later on, he says he had his thumb in front of the "lens" the whole time.
- Atlantis is a mythical city from Greek mythology.
- Baljeet's pose on the clam shell is the same as the painting The Birth of Venus.
- Irving's ability to take pictures with the mind by saying "click" is like that of Cam Jansen.
- You can briefly hear the Titanic theme as Phineas, Ferb, Isabella, Buford, and Baljeet enter the water, the movie Titanic also seems to be a recurring theme in the show.
- "Four corners of Atlantis" may refer to the saying "four corners of the world".
- The musician said "Thank you. Thank you very much" in the style of Elvis.
- Spongebob SquarePants- During the song Atlantis, Ferb is shown drinking tea from his helmet, like Spongebob and Patrick do in the episode "Tea at the Treedome".
- Frank Lloyd Wright was a famous architect. Candace's comment that she was "Frank Lloyd Wrong" is a pun on his name.
- Samurai Jack - Agent P's chainsaw battle against the mutated plants mimics the cinimatic style seen commonly in this show.
- This episode reveals that Candace was once good at making sandcastles and sculptures.
- Irving appears for the third time in this episode (he apparently stowed away in the trunk when Linda stopped for gas).
- Candace wears the same swimsuit from "De Plane! De Plane!".
- When Doofenshmirtz told Perry he was going upwind of him, it was because Perry had defecated in the fertilizer.
- Second time a bag of manure was used ("I, Brobot").
- Ferb's, "Perhaps the lost city of Atlantis wanted to stay lost" echoes, Phineas's, "He must not want the world to know he really exists" ("The Lake Nose Monster").
- Following "Unfair Science Fair Redux (Another Story)", this is the second time the Doofenshmirtz Evil Incorporated jingle plays instrumentally.
- Second time Candace doesn't see the Big Idea ("Hail Doofania!").
