The intro tells the player the speed in which the song must be played to lure the Goombas over to their side. The player uses a small organ grinder-like instrument to play the Super Mario Bros.Ground Theme at a slow, medium, or fast tempo.
The player must use the to turn the crank on the organ grinder counterclockwise at the speed shown in the intro to attract giant Goombas to the player's side of the field. If the song is played at the wrong speed, clear notes will come out of the music player, but colored notes will play if the player has played the song at the correct speed. If the Goombas hear the tune played at the right speed, they will start wandering towards the player that is playing at the right speed. The minigame ends after 30 seconds or when all Goombas on the field have chosen a side. The player that lured the most Goombas to their side wins. If no players had any Goombas or if they have the same number of Goombas in the Duel variant, the minigame ends in a tie.
Rules – "Listen to the tempo of the intro tune, then turn the crank to re-create that speed as closely as possible. The better you do, the more Goombas you'll lure."
Tips – "Your music box will emit colorful notes when you're cranking at the perfect speed."
