Banjo-Kazooie: Nuts & Bolts is a sequel to the N64 game, Banjo-Kazooie. Players explore the world of Showdown Town, which houses Mumbo's Garage - this garage allows players to construct any vehicle imaginable as long as it follows some simple basic rules - it needs an engine, fuel, and a seat for Banjo to sit in. Apart from that, anything from hovercrafts to planes to trucks to rockets to unicycles (and more!) can be created. Showdown Town leads to many more worlds, each created by L.O.G.. These worlds house challenges - it's up to the player to build the most appropriate vehicle for that challenge. Solving each challenge earns Jiggies, which are puzzle pieces used to open up more worlds and finally face off against Grunty herself for the grand prize - the deed to Spiral Mountain.
