King Banana is an item located in the Challenge Mode of Mario Superstar Baseball. It can be bought at the local store in Challenge Mode, and will enable Donkey Kong's Power Shot, the Banana Ball. The item is only available in the store if Donkey Kong is the team captain, or if he is on another captain's team. Donkey Kong does not need this item in Exhibition Mode, as he can use the Banana Ball anytime he wants. The name of the King Banana comes from it being a Banana, and the term "King of the Jungle", which Donkey Kong has commonly been called. "King Banana" is also a key item in EarthBound, however, this might be a coincidence.
