Dance Dance Revolution: Mario Mix, known as Dancing Stage Mario Mix in Europe and Dance Dance Revolution with Mario in Japan, also known as DDR Mario Mix or just Mario Mix, is a 2005 music video game by Nintendo and Konami for the Nintendo GameCube, and is the first Dance Dance Revolution game to be released on a Nintendo console outside of Japan. Mario Mix features several of Nintendo's popular characters, including Mario, Luigi, Toad, Toadette, Waluigi, Wario, and Bowser. It is notable for being the only game to feature Waluigi in a more prominent role, as an antagonist during one of the game's story mode levels. The game is bundled with the dance pad controller.
