Grape

Grapes are a type of fruit found in the Marioverse and also in Earth. They first appeared in Yoshi's Story as one of the fruit the Yoshis had to eat to clear a level. During the game, Grapes were the favorite fruit of Light Blue Yoshis and Blue Yoshis. Notice that a Purple Yoshi was going to be playable in Yoshi's Story (later taken out) and it is rumored the Purple Yoshi's favorite fruit was going to be Grape.

Grape later appears in the Donkey Kong game, Donkey Kong: Jungle Beat. In the game there is a kingdom called the Grape Kingdom. At the end of every level in the Grape Kingdom was an enormous Grape. This enormous grape had to be eaten by Donkey Kong so he could go to the next level.
