The boys and their friends create a plane that's bigger than Creator/HowardHughes' Spruce Goose, while Candace is jealous of a visiting girl catching Jeremy's attention at his pool party. Elsewhere, Doofenshmirtz attempts to dry up all the pools in the Tri-State Area as part of his "Greevil" campaign.

!!Tropes:

* AllForNothing: Candace tries to impress Jeremy to one-up Nicolette, who brags about the amazing things she's done. Not only did she get hurt trying to impress Jeremy, but Candace learns that Nicolette was talking about a video game. It wasn't entirely for nothing; she got Jeremy's attention and impressed him, and he signed her cast.
-->'''Candace:''' So your ''cousin'' Nicolette was trapped on a video game level?\\
'''Jeremy:''' Yeah, took her a week to get through it. You didn't really think she did all those things?
* {{Anticlimax}}: Dr. Doofenshmirtz's backstory about not being allowed in public pools is just his mother sternly telling him "No."
-->'''Doofenshmirtz:''' What? That's it! You know, not every backstory has to have some big in-depth spiel, Mr. High Expectations!
* ArtisticLicenseHistory: The Spruce Goose is not 319 feet 11 inches, as the show states; it is actually one foot longer in real life. Therefore, since the Paper Pelican is 320 feet even, it technically didn't beat Hughes. Also, Hughes never referred to his plane as the Spruce Goose, he called it the Hughes H-4 Hercules. It was only called the Spruce Goose by the press, and it was a name that Hughes deplored.
* BreadEggsBreadedEggs: This line from Candace:
-->'''Candace:''' Ahem! There's been a lot of talk around here about diving and snakes and diving with snakes and snakes into pools filled with piranha and sulfuric acid—\\
'''Nicolette''': I didn't say ''anything'' about sulfuric acid.\\
'''Candace''': Leave all questions 'til the end of the rant! Thank you!
* CallBack: Ferb sings the song with the microphone covering his mouth, much like in "[[Recap/PhineasAndFerbLawnGnomeBeachPartyOfTerror Lawn Gnome Beach Party of Terror]]".
* ChekhovsGun: When Phineas and Ferb's plane flies above the city, it blocks the sun, shutting down Doofenshmirtz's inator and allowing Perry to kick Doofenshmirtz off his building's balcony before he can reactivate it.
* ContinuityNod:
** Stacy mentioned Candace's jealousy towards the Swedish exchange student D.D., who later turned out to be a guy, for getting Jeremy's attention. Also, she mentioned how Candace was freaking out while on a snowboard with her brothers. Both of these events happened in [[Recap/PhineasAndFerbSWinter "S'Winter"]].
** Also, when Candace is jealous of how "awesome" Nicolette appears to be, Stacy reminds her that "[[Recap/PhineasAndFerbItsAboutTime You've fought dinosaurs!]] [[Recap/PhineasAndFerbUnfairScienceFairRedux You've been to Mars!]] [[Recap/PhineasAndFerbItsAboutTime You've traveled through time!]]" Although, technically, Candace did not actually ''fight'' any dinosaurs, but she did run away from plenty of them.
* DiegeticSwitch: The song "Big Ginormous Airplane" starts as in-flight entertainment provided by Ferb, singing in front of a vintage mic with the appropriate filter, before switching to clear audio soundtrack as the song ramps up. It closes by switching back into diegetic as Ferb finishes singing.
* EpisodeOnAPlane: Phineas and Ferb's plot is this, with Phineas and Ferb acting as pilot and co-pilot, Isabella and Baljeet and the Fireside Girls as the flight attendants and floor show performers.
* FantasyHelmetEnforcement: Parodied; when the pool party turns into a skate party, the other party-goers outfit Candace with a helmet, pads, [[ArsonMurderAndJaywalking and a steering wheel with a driver-side airbag]]. Then Phineas and Ferb's giant plane blocks out the sun and she crashes into Jeremy.
* GreenAesop: Doof's inator is made up of recycled materials. As Doof describes it, "[[BreadEggsBreadedEggs It's green and evil! I call it 'Greevil!]]'" And he opens his lab coat to reveal his shirt has a green recycling symbol on it. His inator is also solar powered.
* HowardHughesHomage: Phineas and Ferb are inspired to do today's idea after watching a documentary on Hughes and his Hughes H-4 Hercules (which was derisively referred to as the "Spruce Goose"). After Phineas says, "I know what we're gonna do today", Ferb briefly is seen with Hughes' hair and mustache when giving a thumbs up.
* HurricaneOfPuns: Phineas and Isabella do some newspaper puns when he reveals he's making the plane out of paper maché.
-->'''Isabella''': Why? To make sure it's ''news''worthy?\\
''(everyone laughs)''\\
'''Phineas''': And ''read'' all over!\\
''(everyone laughs)''\\
'''Buford''': ''(holding the comics page)'' Oh! Oh, oh! Ha! And ''funny''! ''(laughs)'' And ''funny!'' ''([[LamePunReaction no response]])'' Y'know, cuz... [[DontExplainTheJoke cuz the funnies]], heh.\\
[...]\\
'''Phineas''': We're gonna call [our plane] the Paper Pelican, 'cause it's made out of newspaper. Y'know, so it'll have a good ''circulation!''\\
''(everyone laughs again)''\\
'''Buford''': Oh, come on!
* HypocriticalHumor: Candace dreads over which swimsuit she should wear. After she picks one, Stacy asks which hat she should wear and Candace says it doesn't matter.
-->'''Stacy''': You're right, I fuss too much.
* JustPlaneWrong: Phineas and Ferb's giant plane takes off by... tilting upward and then immediately shooting up into the sky, without building up any speed first. They didn't even build a runway.
* LandDownUnder: Nicolette speaks with an Australian accent (she is voiced by Aussie presenter Shae Brewster) and speaks about swimming in a pool of piranha, which are native to Australia. Of course, it turns out she was stuck on a video game level.
* OurSloganIsTerrible: Buford preemptively does not want insignificant packs of peanuts, so Baljeet hastily makes the peanuts into the shape of a rotisserie chicken, claiming it to be a "deluxe peanut chicken", whose slogan is "It is so peanutty, you will not even ''taste'' the chicken!"
-->'''Jingle singers''': So peanutty you won't even taste the chickennnn...
* PlasterCastDoodling: Jeremy signs Candace's cast with a heart with "C+J" inside it, much like Candace wrote a similar heart in "[[Recap/PhineasAndFerbItsAboutTime It's About Time!]]".
* {{Portmanteau}}: Dr. Doofenshmirtz brags that his evil scheme to make a solar-powered evaporating ray out of old bottles is "Both green and evil! I call it 'greevil'!"
* PunctualityIsForPeasants: Parodied, as Stacy has to look at her watch to make sure they are officially "fashionably late" to Jeremy's pool party.
* RelativeError: Candace becomes jealous of Jeremy hanging out with a cool girl named Nicolette. Fortunately, Nicolette is actually his cousin.
* RememberWhenYouBlewUpASun: When giving Candace a pep talk, Stacy brings up the events of "It's About Time" and "Unfair Science Fair Redux".
-->'''Stacy:''' What are you worrying about? You're Candace Flynn!\\
'''Candace:''' Yeah, and she's super-cool, foreign-accent, snake wrestler, high-diving, natural hottie Nicolette.\\
'''Stacy:''' Snake wrestler, whatever! You fought dinosaurs! You've been to Mars! You've traveled through time!
* RunningGag: In this episode, it's Perry flipping in and out of secret passages: in his hideout, in Doof's lair, and at the end, out of the water beside Phineas and Ferb.
* ShoutOut: The title is a reference to Tattoo's CatchPhrase from ''Series/FantasyIsland''.
* VisualPun: Ferb's "co-pilot instruments" are actual musical instruments.
* WhatHappenedToTheMouse: We do not get to see what happens to Doofenshmirtz's inator after Perry kicks Doof off the balcony.
