Wish Keys, otherwise known as Keys, are a set of four keys that appear in Diddy Kong Racing and Diddy Kong Racing DS. Each Wish Key is hidden in a racetrack of all four worlds, and unlock the Challenge Level door of their respective world.
All four Wish Keys are large, golden keys in the original version. Their role was slightly changed in the DS remake, where each Wish Key unlocks a Wish Race against T.T.. Each one also received their own redesign except for the one of Dragon Forest. Most of their redesigns is based on their respective world theme. Dino Domain's key has a skull design, Snowflake Mountain's key is made of ice, and Sherbet Island's key resembles a golden anchor.
