Donkey Kong Bananza is a platforming game directed by Keiji Inafune released on 17 July 2025. It features the titular character, Bananza (voiced by Tim Allen), on an inter-dimensional heist to steal every banana ever so he can extort Donkey Kong and King K. Rool out of their Smash invitations. On his adventure, he encounters Crazy-Rock (voiced by Zach Hadel), a crazy rock that can detect all sorts of bananas underground.
It was originally planned that upon collecting a banana, the game would chant “KOJIMA” instead of the usual “BANANA”. Hideo Kojima was asked permission for this, but had to decline due to creative differences. However, he allowed a Glonpo cameo as a middle-ground. When asked about the situation, game director Inafune replied with: “It's better than nothing”. It is often speculated that this dispute is what started the tense rivalry between Inafune and Kojima.
