Xananab is a mysterious creature shaped like a banana. His first and only appearance so far was in DK Jungle Climber. He meets Donkey Kong and friends after they accidentally destroy his ship on Sun Sun Island, mistaking him for an enemy. Xananab is originally from the planet Plantean. Xananab helps Donkey Kong throughout the events of DK Jungle Climber by activating special wormhole machines so Donkey Kong can travel to different dimensions to complete levels. Xananab also provides tips to aid Donkey Kong during levels.
- Xananab is BananaX backwards, a reference to an alien origin.
