Unseen64 has uncovered yet another unreleased game, this time in the popular Banjo-Kazooie series. Banjo-Kazooie: Grunty's Revenge, released for Game Boy Advance in 2003, drew much of its inspiration from a cancelled Game Boy Color game called Banjo-Kazooie: Grunty's Curse, but there were some big differences.
Instead of traveling back in time to prevent Banjo and Kazooie from meeting, Grunty turns Kazooie into an evil, blue monster version of herself and carries her around in a backpack. Grunty's Curse was planned to have eight levels, and five of them were renamed and re-purposed in Grunty's Revenge, while two others were merged together. It was also planned to feature some of the transformations from the main series games, as well as some funny "useless transformations" like Toaster Banjo and Milking Machine Banjo.
