Smokey Castle

Smokey Castle is a challenge level found in Dragon Forest in Diddy Kong Racing and its remake, Diddy Kong Racing DS. It becomes accessible after the player's racer collects the Wish Key of Boulder Canyon.

The battle takes place in a square-shaped castle. Inside the castle are four treasure chests, each depicting the character that it belongs to. The purpose is for racers to collect bananas and take them to their treasure chest. Racers can only carry up to two bananas at a time. Racers can steal bananas from their opponents by hitting them with a weapon. Once bananas have been placed on a chest, they cannot be stolen. The first racer to put ten bananas into their treasure chest wins. If the player's racer wins, they obtain the fourth and final piece of the T.T. Amulet.
