Banjo-Kazooie: Nuts & Bolts (2008)

Banjo-Kazooie: Nuts & Bolts — It's been 8 years since Banjo-Tooie. Since then, only a skull has remained of the old witch Gruntilda, the main antagonist, and Banjo and Kazooie have become lazy and fat wasters of life. The heroes and the half-dead skull of Grunty meet at Spiral Mountain. But in response to the witch's threats, Banjo and Kazooie laugh uncontrollably. But they are all suddenly interrupted by something calling itself the Lord of Games. He decides to resolve another conflict between them, and returns Banjo and Kazooie to their former physical form, but at the same time he also gives a new mechanized body to Gruntilda. He says they won't need their past skills and makes them do some racing tests on cars they have to build themselves. The winner regains possession of Spiral Mountain, and the loser is forever sent to hard labor to the Lord of Games.
