Perry the Platypus

Perry the Platypus is an anthropomorphic platypus who belongs to Phineas and Ferb in the Disney Channel cartoon, Phineas and Ferb. Unknown to his owners, Perry lives a double life as a secret agent called Agent P. Perry enters his lair under the house through many tube systems, the "Chimneylator" (an elevator in the chimney) and many other entrances. He fights a mad scientist named Dr. Doofenshmirtz. Perry always accomplishes is missions to stop the doctor's plans. A running gag in the show is that his missions end up covering up evidence of Phineas and Ferb's activities by accident, therefore Linda never finds out about the boys' schemes.While Perry never says anything throughout the show, like all platypuses, Perry can make a growling noise that he uses at random times.

Personality
Perry acts almost unaware of his surroundings when he is around his owners. But he actually smarter than he looks. He cares for his owners, as seen in episodes " Journey to the Center of Candace" and "The Ballad of Bad Beard". He seems to know the way out any situation, as anytime Dr. Doofenshmirtz captures him, he easily escapes.
