Episode Summary
are watching an old sci-fi movie about a man who created a teleport device. Phineas decides to create their very own teleport device. Linda crawls in and asks the boys if they have seen her earrings, and Phineas tells her that they'll keep an eye out for it. Phineas and Ferb run out to the garage and start building their teleport device.

Candace wakes up and sees Perry sleeping on her bed. She picks Perry up and goes outside to tell her mom that Jeremy is coming over and not to embarrass her. Candace goes into the garage and sees the teleport device. Candace trips on a wire in the garage and falls into the teleport device with Perry. This causes them to switch brains, which worries Candace because Jeremy will be there any second. Phineas tells Candace that they'll switch them back in no time, but when they turn around, Perry in Candace's body has gone off to his lair.

Perry meets Major Monogram and Carl at his lair, where they think that he is wearing a teenage girl disguise. Perry realizes that they must've switched brains, but this doesn't stop him from defeating Dr. Doofenshmirtz. Perry rushes over to the Doofenshmirtz Evil Incorporated building, where Dr. Doofenshmirtz explains to him that the jingle emanating from Slushy the Clown figures irritate him, so he has decided to take out the tapes and replace them with his own evil jingle.

Meanwhile, Phineas and Ferb decide to put up fliers of Candace holding Perry to help them find Perry in Candace's body. Jeremy arrives and feeds Candace with platypus food, which Candace realizes is dead worms. She spits it out and Linda puts her outside. Perry defeats Dr. Doofenshmirtz by wrapping him in iPod wires and returns all of the Slushy the Clown figures at their rightful place. He returns back to their house.

Phineas and Ferb arrive back and see Perry. They immediately rush to their garage, where Candace holds Perry and walks through the teleport device. Candace immediately tries to bust Phineas and Ferb and runs inside the house. Dr. Doofenshmirtz cannot move, so he has to navigate himself by jumping. He loses his balance and hits his Shrink-inator from a previous episode. The Shrink-inator hits the teleport device and shrinks it so that it looks like small hoops. Linda arrives in the garage and thanks Phineas and Ferb for building her earrings.
