Ninja Fruit

Ninja Fruit or Ninja Apple is a mysterious fruit who lives in his dojo under the oven and an expert in the ancient art of the Ninja Fruit.

He was the secondary protagonist of the episode "Kung Fruit". He meets Orange there and trains him to become a master of Kung Fruit and gives him a ninja suit. Orange thanks him for helping him defeat Coconut, but in the end, he says he still wants the suit back as it was only a loaner.
