Mappy (マッピー, Mappī) is a 1983 arcade game by Namco. In the United States, it was distributed by Bally/Midway. Mappy is a side-scrolling platform game that features cartoon-like animals, primarily cats and mice. The game's main character itself is a mouse. Mappy runs on Namco Super Pac-Man hardware, modified to support horizontal scrolling. The name "Mappy" is likely derived from mappo, a Japanese slang term (slightly insulting) for a policeman.
