Pinky is Brain's silly sidekick and the duetergonist in the Warner Brothers cartoons, notably Pinky and The Brain and the secondary antagonist of Wakko's Wish. Just like Brain, Pinky is a genetically modified mouse. He has a straight tail, blue eyes, and a severe overbite. He is taller than The Brain. Pinky shares Brain's cage at ACME Labs. He is significantly dimmer than his genius cagemate and speaks with an exaggerated cockney accent. He has several verbal tics, such as "narf", "zort", "poit" and "troz" (the latter of which he started saying after noticing it was zort in the mirror).
