Stimpson "Stimpy" J. Cat is a 3-year old (28 in cat years) fat, dim-witted, and rotund red and white Manx cat with a brain that's literally the size of a peanut. He has a big, blue nose, dark blue eyes which can only be seen in close ups, flat feet, no tail, human-style buttocks, and a pair of white gloves. He invents dangerous machines and can cook. His favorite song is "Happy Happy Joy Joy". Martin "Dr. Toon" Goodman of Animation World Magazine described Stimpy as "obese," and "brain-damaged." Andy Meisler of The New York Times described Stimpy as "bosom," "barrel-chested," and "good-natured." He often has his tongue sticking out and usually says "Oh, Joy". He likes to watch cartoons, most notably "The Muddy Mudskipper Show" and use Gritty Kitty Litter. Stimpy's good-natured personality is the opposite of Ren's personality. He is voiced by Billy West in The Ren & Stimpy Show. In the short lived spin-off series Adult Party Cartoon, Stimpy was voiced by Eric Bauza (who had worked on the series along with the originals).
