Smokey Castle

Smokey Castle is a battle minigame in Dragon Forest in the game Diddy Kong Racing and its remake, Diddy Kong Racing DS. It becomes accessible after the player collects the golden key in Boulder Canyon.

The purpose of the treasure chests is to hold Bananas which the racers collect. During the game, a racer can hold a maximum amount of two bananas, so after collecting two of them, s/he should put them into his or her respective treasure chest. After one racer has collected ten bananas, s/he will win the challenge and be rewarded with a piece of the T.T. Amulet.
