The Truffle Towers is a small castle appearing in Dance Dance Revolution: Mario Mix. The Music Keys, which keep the Mushroom Kingdom safe, are held within the castle. Once Waluigi releases the Music Keys during the events of the game, he gets one of them in order to become the best dancer. Mario (or Luigi) and Toad arrive at the Truffle Towers in an attempt to stop Waluigi, but the doors are locked. Once Mario and Toad find the key, they enter and challenge Waluigi to a dance-off.
