Koopa Troopa Beach (court)

Koopa Beach is a beach, in Mario Hoops 3-on-3. It is a playable court in the Mushroom Tourney. In the background there are two surfboards that have an M and L on them. There is also a pirate ship on the water in the background, that can sometimes shoot bombs in the field. If a player gets hit by it, he or she will fall down and loose the ball. Also, players move slower when playing in the surf on either side of the field. The course doesn't have an audience. Strangely, there are no Koopas on the field, only a green shell design hanging over the court.

It is possible that Koopa Beach is a throwback to the Koopa Beach courses (such as Koopa Beach 2) of Super Mario Kart.
