Phineas and Ferb

Phineas and Ferb is an original series of Disney Channel but also transmitted by Disney XD, and created by Dan Povenmire and Jeff "Swampy" Marsh. It premiered on August 17, 2007, at the same time on Disney Channel internationally.

The series follows the adventures of the young and intrepid pair of stepbrothers Phineas Flynn and Ferb Fletcher, along with their friends Isabella, Buford and Baljeet, who live out of the ordinary adventures thanks to the inventions of the two characters initially mentioned. At the same time, their older sister Candace wants to bust her brothers to her mother. In addition, Perry (mascot and secret agent) must prevent Heinz Doofenshmirtz from doing some evil against society (he is a mad scientist).

Attack of the 50 Foot Sister
Candace and Stacy are watching television in Candace's room. Stacy reads from a Flawless Girl magazine that the Flawless Girl founder, Blanca Dishon, will be at the Midsummer's Festival later today to search for the next Flawless Girl. Candace feels confident that she might have a shot at being the next Flawless Girl, so she decides to head to the festival and try out for herself. Outside in their backyard, Phineas and Ferb get a signal from Baljeet. He asks them to help him grow his shrunken watermelon at the Midsummer's Festival since they helped him build his portal to Mars. Phineas agrees to help him and tells Ferb that they're going to the festival.

Perry the Platypus enters his lair through a koi pond along with three other fish, whom Major Monogram hires as secret agents. He tells Perry to go see Dr. Doofenshmirtz.

Meanwhile, Phineas and Ferb meet Baljeet at the Midsummer's Festival. Ferb takes out his chemistry set and Phineas and Ferb create a growth elixir to help grow Baljeet's watermelon. But when they put a few drops on Baljeet's watermelon, it only grows a few inches. Candace arrives at the festival and meets P. P. Otter, but tells him that she doesn't need his help. She heads off to the Flawless Girl booth, where Blanca sits. Blanca tells Candace to stand over by a measuring post and tells her that she is two inches too short to be the next Flawless Girl. Candace walks away with her new Flawless Girl products and sees Phineas and Ferb with their growth elixir. She pours some on herself and it makes her taller by two inches. Candace runs back to the Flawless Girl booth and is told that she is in the running to be the next Flawless Girl.

Baljeet's watermelon grows to be the biggest watermelon at the festival. At the same time it grew, Candace begins growing taller as well. Soon enough, she becomes a 50-foot tall giant. She runs into a tent to hide, and asks Phineas to make a shrinking antidote. Phineas tells her that they'll get on it. P.P. Otter walks over and gives Candace his card, after seeing her with a giant head. He walks away and Candace begins to cry, saying that she will never be a Flawless Girl. She decides to go to P.P. Otter and his oddball show.

Perry enters Doofenshmirtz's building, interrupting The Slacks singing his evil jingle. Doofenshmirtz traps him in a baby toy, telling him about the baby shower he went to the other day. He says that he has created a device that will cover the entire Tri-state area with the smell of dirty diapers, as he is annoyed by the noise of the Mid-Summer's Festival.

P.P. Otter tells Candace to climb a skyscraper carrying him dressed in a gorilla suit (in a reversed twist of King Kong). Candace climbs the Doofenshmirtz Evil Incorporated building.

Inside, Doofenshmirtz shows Perry his Smell-inator. When Candace reaches the top of the building, Blanca spots her and decides that Candace is the next Flawless Girl, then she takes the elevator up to top of D.E.Inc. and tells Candace that she's the next Flawless Girl. But Candace can't hear her. So she picks Blanca up in her hand.

Blanca says that girls will never be able to live up to Candace's expectations, and P.P. Otter argues with her. However, Candace realizes that both of them make money off of people to make people feel worse about themselves. She leaves Blanca and P.P. Otter on top of the building and climbs down to bust Phineas and Ferb.

Candace leaves her growth elixir on top of the building and P.P. Otter grabs it to make money. However, when Blanca wrestles it out of his hands, it falls near Doofenshmirtz's invention, replacing the flask that smells like dirty diapers with the growth elixir. Right when Candace is about to show her mom that Phineas and Ferb had made her into a giant, Doofenshmirtz activates the invention, causing the entire universe to grow bigger, making it look like nothing ever happened. Perry escapes and covers the Doofenshmirtz building with his dirty diaper smell. And because of this Baljeet loses the contest and goes home to put up the shame curtains.
