Wario Dunes

Wario Dunes is a sand court in Mario Tennis Open. It is set in a desert, as a cactus appears, and an Egyptian pyramid appears in the background. It has ruined sand bricks surrounding the court, and it is heavily based on Super Mario desert levels. Unlit torches with their design taken from Super Mario Galaxy also appear. Red, Green, and Pink Shy Guys appear surrounding the court. The bounce of the court is weak and the ball speed is slow, which makes the ball travel at a slower velocity. Wario Dunes is the default court when one plays Flower Cup tournament.

Wario Dunes has a very similar layout to the Wario Court in Mario Tennis 64. Both are set in the desert and both are notable for having very low ball speed and bounce.
