Goronade

Goronade, an energy drink, is given to Link by the Goron guarding the steps to the upper part of Rolling Ridge in trade for the Goron Vase. Link then must give the Goronade to the Goron running the Big Bang Game so that he can then play the game and win the Old Mermaid Key.

Trivia
The name "Goronade" seems to be a play on the popular energy drink "Gatorade", or simply a combination of 'goron' and 'lemonade'.
