Pinky the Chihuahua is Isabella Garcia-Shapiro's pet chihuahua. Though by outward appearance he is a mindless animal, it has been revealed that he, like Perry the Platypus, is a secret agent (specifically in Wanda's Division). He, like Perry, is codenamed Agent P, but is more commonly referred to as Pinky or Agent Pinky. His nemesis is Professor Poofenplotz.
