Perry the Platypus (& other names called by Phineas is Perry or Agent P) is a teal undercover secret agent platypus and the main character of the game "Where's My Perry?". He needs to go down to the tube for a briefing from Major Monogram. His enemy is Dr. Doofenshmirtz.
Like Swampy, the player must collect the gnomes and free him by filling up with water. If the player wastes all the water, Dr. Doofenshmirtz will tell him that Perry wants more water. However, Doofenshmirtz says that Perry can't have his.
