It's an actual submarine sandwich submarine. I can't believe we hadn't thought of it sooner.

— Phineas Flynn

The kids build a giant submarine sandwich submarine (out of actual food), to explore the Mariana Trench. Meanwhile, Doofenshmirtz's latest invention steals food for him while his oven is broken and he awaits a visit from the repairman.

Episode Summary[]

In the backyard, Phineas and the gang are putting the finishing touches on their latest creation, a submarine that resembles a submarine sandwich. As Candace spies on them, she gets a call from her mom reminding her that today will be the day of the sandcastle building competition. Phineas explains to the gang that they will use their sub to plant their flag in the Mariana Trench, the deepest part of the ocean.

Meanwhile, Perry enters his lair to find Major Monogram having some technical problems with the filters, making him resemble a sock puppet. Monogram informs him that Doofenshmirtz has been stealing food. When he reaches Doof's lab, Doof explains that he has been waiting the arrival of his oven repairman, who gave him a ridiculously long window of time. Since he has to be in his apartment until the repairman comes, he cannot make any food, so created the Fork-It-Over-inator to steal food from people's plates.

After the gang complete their sub, Candace stows away in an attempt to bust the boys as a helicopter carries the sub into the ocean. Once they reach the ocean, they plant their flag in what appears to be the Mariana Trench, but turns out to be a giant hungry fish monster, who gives them chase. The gang intend to use the escape vehicle to get away, but unfortunately, Buford ate the handle to the escape hatch, which was made of bread. So the gang instead use the escape sub as bait to feed the hungry fish monster, and make their way back up to land, as Candace approaches her Mom.

Back at Doof's lab, Doof has stolen enough food to feed him for weeks, but Perry kicks him into the inator, which latches onto the submarine sandwich submarine. As Doof gets pulled into the beach, he crashes into several sand sculptures before burying the submarine sandwich submarine in sand. When Linda and Candace arrive, Linda mistakenly believes this was Candace's entry in the contest, which she ends up winning.

At Doof's apartment, the oven repairman finally arrives, but leaves, since Doof is no longer there, having missed the window.

Memorable Quotes[]

Doofenshmirtz: Y'see, I'm stuck here waiting for my oven repairman who gave me a ridiculous window. And not this ridiculous window of me kicking an orange. Long story, don't even ask. I'm talking about a ridiculous window of time.
Baljeet: And a little extra yeast in the baguette will increase our overall maneuverability.
Buford: And what's the science behind this?
Baljeet: Please save your questions till the end.
Buford: Is it the end?
Baljeet: No! And that is also a question.
Linda: Please, honey, don't tell me this is about the boys. Is this about the boys?
Candace: You just told me not to tell you.
Linda: Can you hear how disappointed my face looks?

Background Information[]

Production Information[]

  • This episode was previously titled "Appetite for Adventure".
  • A clip from this episode was shown during Ashley Tisdale's appearance on Live with Kelly & Mark on ABC on May 28, 2025.
  • The shot where Isabella shows Buford her sash full of safety patches was animated in-house at Disney Television Animation.

International Premieres[]

Errors[]

Continuity[]

  • Buford is still upset that he hadn't gotten his bread bowl hot tub yet. ("Summer Block Buster")
  • While Doofenshmirtz is getting pulled off of his building by his inator, there is a billboard advertising Wind-Con. ("Cloudy with a Chance of Mom")
  • Candace returns to the sand castle building competition she accidentally won. ("Atlantis")

Allusions[]

  • "Wellerman" - The song is patterned after a New Zealand whaling song (erroneously identified as a sea shanty) that went viral on TikTok during the COVID-19 pandemic.
  • Kid vs. Kat - The sea monster resembles Bongo Boingo from the Kid Vs. Cat episode Something Fishy In Owl Lake.
  • Press Your Luck - At one point, Doof says, "Big money, big money, no whammy!", which is a catchphrase from this game show first hosted by Peter David Tomarken and currently hosted by Elizabeth Banks. On the show, the "No whammies" line was referring to an animated devilish-like imp named the "Whammy", who would take away all the contestant's money. If the contestant got four Whammies, they were eliminated from the game.

Trivia[]

  • This is the second time Mom and Candace take part in a sandcastle building competition. ("Atlantis")
  • Doofenshmirtz is shown to have a punch clock.
  • This is the first episode (excluding movies) to feature the "Oh, there you are, Perry" line since "The Return of the Rogue Rabbit".
  • Lawrence is absent in this episode.
  • Starting from this episode until The Candace Suit/Agent T (For Teen), in the "Phineas and Ferb Theme", the phrase "There's 104 days" is changed to "There's another 104 days".
    • In addition, Phineas's Season 1 voice, which had remained constant in the theme from Seasons 1 to 4, is now replaced by his current voice.
  • It's revealed that Baljeet has five years of violin lessons.
  • Fifth time Doof does the "Hey, is that [band name]?" joke. When he crashes into a sand sculpture of Love Händel he says, "Hey, is that Love Händel?" in reference to the first use of the joke. ("Dude, We're Getting the Band Back Together", "The Baljeatles", "Meatloaf Surprise", "Thanks But No Thanks")
  • Doof never once calls his nemesis "Perry the Platypus", instead trying out calling him by his "given" name. But since he doesn't know what that is, he tries out "Pericles", "Periodontal" and "Periwinkle the Platypus".
