Banjo-Kazooie: Grunty's Revenge Mobile was a game that was released for the mobile phone. Its storyline and gameplay are very much similar to its Game Boy Advance version, but the graphics and sound vary. It was released in July 2004, approximately one year after the Game Boy Advance version. It is the only mobile game in the series that carries the Adventure genre. The levels in the game have the same themes and names as in the Game Boy Advance version, but they are much smaller in size. Banjo and Kazooie do not have as many moves, and there are no Mumbo Jumbo transformations.
