After his defeat in Diddy Kong Racing, Wizpig allies himself with the Kremlings to get his revenge. While Diddy Kong is away on a visit to Timber Island, the Kremlings have been kidnapping members of the Kong clan, while Wizpig is in the process of converting Kongo Island into a gigantic raceway. Upon returning and seeing the Kremlings bulldoze the forest, Diddy Kong gathers the racers of the original Diddy Kong Racing to challenge Wizpig and stop his destruction of Kongo Island.
