 Links Awakening features many references to Super Mario games.  Among them are the Yoshi Doll (modeled after the Mario character of  the same name) and several enemies/characters in the game, including  Goombas, Chain Chomps, Boo Buddies, Piranha Plants, and Wart.  Incidently, the Zelda games and the Mario games were both conceived  by the same man, Shigeru Miyamoto.
