Rattle and Hmmm

Rattle and Hmmm is a free-for-all minigame appearing in Super Mario Party. Its name is a nod to the  album by Irish band.

Gameplay
In this minigame, players must pay attention to the rumble in the Joy-Cons that three enemies make. After all enemies have performed, the players must listen to the rumble sequence and select the enemy that best matches the rumble sequence. The first player to answer correctly gets five points, the second player to do so gets three points, the third player gets two points, and the fourth player gets one point. Players who answer incorrectly are yielded zero points.

After three rounds, the player with the most points wins.
