The four players stand on the playfield as water suddenly appears to fall down onto them. When that is done, the water starts to form a bubble as it captures all the players there. The bubble hovers from the ground after forming as the minigame starts.
The players attempt to knock each other around outside the bubble. The players can knock a player by punching them. Players also can swim around the water bubble to try to avoid being punched. One trick to avoid being forced out of the water bubble is to try to stay in the center of the bubble. The last player who is left inside the water bubble wins. However, if there is no sole winner in 60 seconds, the players who are left standing all win.
The minigame background takes place in some type of temple. The sky is crystal clear in the day, and there is a rainbow on the left side of the sky and tow flags on the right side as minor backgrounds. Waterfalls additionally appear as the water from them moves down around the center of the water bubble. Water also moves down from the stone staircases. There are also two Cheep Cheep statues that spit out water.
The camera zooms in on the winner(s) as they do their victory animation(s).
