According to developer Gregg Mayles, Banjo-Kazooie: Nuts and Bolts was actually the third attempt at creating 'Banjo-Threeie', the third installment in the main line of the franchise. The first attempt was supposedly Banjo X, an unfinished build for the original Xbox which featured some new assets and items. The second attempt, was a re-make of Banjo-Kazooie with some twists, and would have possibly featured Gruntilda following the duo around different worlds and trying to outdo them.
