Banjo-Tooie is a platform video game developed by Rare and originally released for the Nintendo 64 console in 2000. It is the second game in the "Banjo-Kazooie" series and the sequel to "Banjo-Kazooie". The game follows the returning protagonists Banjo and Kazooie as they attempt to stop the plans of the witch Gruntilda and two of her sisters, who intend to vaporise the inhabitants of the game's island setting. The game features worlds significantly larger than those of its predecessor, requiring the player to complete challenges such as solving puzzles, jumping over obstacles, collecting items, and defeating opponents. It also includes a multiplayer mode where up to four players can compete in several minigames repurposed from the main campaign.
