Wario Dance Company (WarioWare: Smooth Moves)
From the Super Mario Wiki, the Mario encyclopedia
Wario Dance Company is Tiny Wario's boss microgame in WarioWare: Smooth Moves. It is the final mandatory boss microgame of the game. If counting Boom Box from Orbulon's optional stage, it is the penultimate boss microgame in the game.
During the game, four strange 3D characters that have Wario's nose and mustache are lined up, and they dance. The player plays as the purple character in the very back. The person in the front will perform a series of moves that is repeated by each person in line. The player must repeat each move or else they are booed at and lose the microgame.
