Horace was presented as Mickey Mouse's four-legged plow horse. He could walk upright on his hind legs, at which time his forelegs became gloved hands; at other times, he got back down on all fours and reverted to form. He is an anthropomorphic horse, one of Mickey Mouse's best friends. Characterized as a cheerful know-it-all, Horace helped Mickey on his sleuthing expeditions in the comics before Goofy assumed that role.
