Manbo

Manbo is a large, green ocean sunfish who appears in The Legend of Zelda: Link's Awakening. His name is a play on the dance "mambo," as well as マンボウ (Manbō), the Japanese word for ocean sunfish. Manbo lives with two fish in a cave near Angler's Tunnel.

History
Link must visit Manbo in his cave to learn Manbo's Mambo, provided that he has an Ocarina. When Link plays Manbo's Mambo, he is brought to the pool outside Crazy Tracy's hut if on the overworld. If Link plays the song while in a dungeon, he is taken to the dungeon's entrance.
