Banjo-Kazooie: Grunty’s Revenge for the Game Boy Advance is the first and only handheld entry in the beloved Rare series, serving as a direct bridge between the original Banjo-Kazooie and Banjo-Tooie. Set two months after the first game, Gruntilda’s spirit has possessed a mechanical suit and kidnapped Kazooie, forcing Banjo to travel through time to save his partner.
