In 2004, another attempt at a sequel for Diddy Kong racing was made, this time as more of a follow-up to the original called Diddy Kong Racing Adventure. The game would've been released on the GameCube, and would've been developed by the UK game studio Climax Studios.

The story of the game focuses on Wizpig seeking revenge on Diddy by teaming up with the Kremlings to turn Kongo Isle into a series of race tracks. Diddy gets his buddies to stop Wizpig and the Kremlings to take back Kongo Isle.

Climax presented the demo of Diddy Kong Racing Adventures to Nintendo, but they didn't give Climax approval to develop the game.
