Banana Juice

Banana Juice is an item from Donkey Kong Country Returns and Donkey Kong Country Returns 3D. 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 Gold Mario. Also it can be used by Diddy Kong in two-player mode. Whenever Donkey Kong or Diddy 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 or Diddy 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 or Diddy 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.
