Phineas and Ferb's pet platypus, Perry, is actually Agent P!!
Just think about it, man! Whenever he disappears, we cut to agent P getting his mission, and he doesn't appear again until Doof is thwarted! Also, his name begins with P!! Coincidence??!! I! Think! NOT!
My god... This makes so much sense...
I doubt it. After all, he is just a platypus. They don't do much.
