World 3 (Dance Dance Revolution: Mario Mix)

Wario's Carnival is a carnival in Dance Dance Revolution: Mario Mix that (presumably) belongs to Wario. Mario (or Luigi) and Toad must go here to get the third Music Key. The entrance is blocked by two Hammer Bros.

After Mario danced off against them, he was able to get into the park where he found Wario running with the Music Key. Wario got into a roller coaster, and Mario followed him. Wario then kept escaping with the Music Key, followed by Mario and Toad. Wario got into a Ghost House filled with Boos. After Mario and Toad escaped the Ghost House, they kept following Wario. Then, a Chain Chomp appeared and chased Mario.

After Mario and Toad escaped the Chain Chomp, they finally caught Wario. Wario then said that he would only give the key to Mario if Mario won the dance off against him. After Mario won, he left the park. An attraction at this Carnival is Dance Dance Revolution: Wario Mix.
