Mumbo Jumbo was introduced in Banjo-Kazooie, released by Rare for the Nintendo 64 in 1998, as the skull faced shaman who transforms Banjo into animals and objects in exchange for Mumbo Tokens. His Eekum Bokum chant became one of the game's most quoted sounds, repeated every time players visited Mumbo's Skull. The phrase survived through sequels, replays and speedruns, then spread online as a short soundboard clip for magical changes. Its gibberish delivery makes it recognisable even to players who have not touched the game in years.
