Perry the Platypus

Perry the Platypus is an anthropomorphic platypus who belongs to Phineas Flynn and Ferb Fletcher 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. Heinz Doofenshmirtz. Perry always accomplishes his 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 or teeth chattering that he uses at random times.

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

 * Phineas Flynn

While for most of the series Perry's relationship to Phineas is unknown, In the episode "Journey to the Center of Candace," he attacks Dr. Doofenshmirtz with unbridled fury when he realizes that the doctor's "Make Up Your Mind-inator" will destroy Phineas and Ferb.


 * Ferb Fletcher

Perry's relationship to Ferb is possibly the same as Phineas. It is also hinted in the episode "Mom's Birthday" that Ferb may own him seeing as how Candace drops him on his lap saying "I beleive this is YOURS."

However, in the episode "Mom's Birthday", in the end, she says, "Where have you been, Perry? You missed all the fun." She says this while petting him, meaning she cares for him.
