Screwball "Screwy" Squirrel is a cartoon character, an anthropomorphic squirrel created by Tex Avery for Metro-Goldwyn-Mayer. He is generally considered the wackiest of the screwball cartoon characters of the 1940s, which included Warner Bros.' Bugs Bunny and Daffy Duck, Disney's Aracuan Bird, Terrytoons's Heckle and Jeckle and Walter Lantz's Woody Woodpecker.
