Banana Juice is an item in Donkey Kong Country Returns. It is a chemistry-like vase with yellow liquid and a star on its outer cover. It is sold and can be purchased at Cranky Kong's Shop for twenty Banana Coins. If Donkey Kong drinks it, the juice will grant him ten additional Hearts, and cause his body to become golden in appearance. Although it cannot be used by Diddy Kong in two-player mode, if Diddy Kong gets on Donkey Kong's back, they will share the Hearts, and both the two of them appear golden. Whenever Donkey Kong loses an extra Heart, but has at least one remaining, he will brieftly revert to normal appearance, before reverting back to golden. The additional Hearts granted by Banana Juice are only temporary. Since they do not increase Donkey Kong's maximum health like the Heart Boost does; once an extra Heart is lost, it cannot be restored. Also, the effect will be lost entirely if Donkey Kong loses all ten additional Hearts or loses an Extra Life Balloon due to something fatal such as falling down an abyss. The effect of Banana Juice also wears off if the Kongs complete a level or quit prematurely.
