Banana Juice

Banana Juice is an item from Donkey Kong Country Returns. It can be purchased from Cranky Kong's Shop for twenty Banana Coins. If Donkey Kong drinks it, it will grant him ten additional hearts, and cause his body to become golden in appearance, not unlike Metal Mario. Although it cannot be used by Diddy Kong in two-player mode, should the monkey get on Donkey's back, they will share the hearts and both appear to be golden. Whenever Donkey Kong loses one of the extra hearts, but has at least one remaining, he will briefly revert to their normal appearance, before reverting back to gold.

The additional hearts granted by Banana Juice are only temporary, as they do not increase Donkey Kong's maximum health like a Heart Boost does; once an extra heart is lost, it cannot be restored. Also, the effect will be lost entirely should Donkey Kong lose all ten extra hearts, or lose a life due to something fatal; such as falling down an abyss. The effects of Banana Juice will also be lost if the player either completes a level or quits prematurely.
