One day, Heinz Doofenshmirtz was waiting for Agent P’s daily visit. He waits a little while and wonders where Perry is. Then he remembers that the last time Perry fought him and destroyed his -Inator he planted a permenent homing device on the platypus’s fedora. Heinz pushes the button and an electronic voice says, “Locating: Perry the Platypus. Location found. Touch screen to continue.” Heinz touches the screen. “I’ve got you now, Perry the Platypus…” he says in his thick German accent. He writes down the adress and goes to Phineas and Ferb’s house. In the backyard, Phineas and Ferb are creating a fancy machine. “Hey, Ferb,” Phineas says looking urgent, “I gotta use the bathroom.”
