It is played in a circular combat arena and has two players, each holding a bell that represents the harvest. When one of the player's bells is knocked out of their grip, and the other player grabs it, they lose that round. The round is also lost instantly if they are thrown out of the ring. If this happens 3 times, the player loses the game.
Fi is an expert at the game and challenges Kat to it at two points in the game.
