Mickey Mouse is an animated character created by Walt Disney and Ub Iwerks. A cheerful anthropomorphic mouse, Mickey made his first public appearance in Steamboat Willie, on November 18, 1928. Estimated as standing 2' 3" (68.58 centimeters) and weighing 23 pounds (10 kilograms), Mickey is easily identified by his round ears, red shorts, white gloves, and yellow shoes. He speaks in a falsetto voice, and his speech is typically infused with 1930's slang like "swell" and "gee".
