Xananab is a mysterious alien creature shaped like a banana who makes his first and only appearance so far in DK: Jungle Climber. He meets Donkey Kong and his friends after they accidentally destroy his ship on Sun Sun Island, mistaking it 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 other levels. Xananab also provides tips to aid Donkey Kong during the game. The player actually owes him, since when his ship was destroyed, his Crystal Bananas were scattered.
- Xananab's name backwards is "BananaX".
