Robot Kremling Head
Donkey Kong, Diddy Kong, Cranky Kong, and Xananab pursue King K. Rool and four Kritters into the Toybox to retrieve the Crystal Bananas from them. When they encounter each other, King K. Rool leaves with three of the Kritters while one of them uses one of the Crystal Bananas to mutate into the Robot Kremling Head and fight the heroes.
The Robot Kremling Head floats around and tries to stab the Donkey Kong and Diddy Kong with knives, as well as shoot at them with missiles and boomerangs. When the battle starts, the Robot Kremling Head is green. In order to damage it in this state, Donkey Kong must attack it in a place where the knives are absent. Once this is done, the Robot Kremling Head turns red with two knives at its bottom and attacks downwards. If the Robot Kremling Head misses the Kongs, the knives get stuck in the tires at the bottom of the battlefield, leaving the Kritter inside it vulnerable. Donkey Kong must attack it while in this state, after which the head reassembles and it turns green again. This process must be completed twice more to defeat the Robot Kremling Head.
Once the Robot Kremling Head is defeated, it is destroyed and the Kritter returns to normal before being defeated, releasing the Crystal Banana.
