Super Monkey Ball is a 2001 platform party video game developed by Amusement Vision and published by Sega. The game debuted in Japan at the 2001 Amusement Operators Union trade show as Monkey Ball, an arcade cabinet running on Sega's NAOMI hardware and controlled with a distinctive banana-shaped analog stick. Due to the failure of Sega's Dreamcast home console and the company's subsequent restructuring, an enhanced port dubbed Super Monkey Ball was released as a launch title for the GameCube in late 2001, garnering interest as Sega's first game published for a Nintendo home console. Conceived by Amusement Vision head Toshihiro Nagoshi, Super Monkey Ball involves guiding a transparent ball containing one of four monkeys—AiAi, MeeMee, Baby, and GonGon—across a series of maze-like platforms.
