Fowlmouth is a cartoon character from the Warner Bros. animated television series, Tiny Toon Adventures. He appears occasionally on the show. Fowlmouth is voiced by Rob Paulsen.
Fowlmouth is a young, white male rooster, who wears a blue short-sleeved shirt and black and gray high tops. He attends Acme Looniversity and lives in Acme Acres. Fowlmouth is based on his mentor and favorite teacher, the loud and pompous Foghorn Leghorn, though speaking in a New Yorker accent as opposed to a Southern United States accent. His high-pitched voice and angry temperament are also reminiscent of Foghorn's occasional rival, Henery Hawk.
When he is introduced in the Test Stress episode segment, To Bleep Or Not To Bleep, he appears to have a mellow personality, but in reality he has a tendency to explode into bleeped out graphic swearing in less-than-favorable situations and also seems to let off swear words for no reason at all when he talked. Buster Bunny remarks, "Fowlmouth swears so much, his beak has been declared a toxic waste dump." Fowlmouth is later cured of this habit per request (in order to score a date with Shirley the Loon with whom he has a crush on), when his refusal to curse in front of babies is exploited. He has since replaced swearing with the euphemism, "Dad gum."
