Wario Court

The Wario Court is a tennis court that appears in Mario Tennis for the Nintendo 64. Like in the Wario & Waluigi Court and the Waluigi Court, the background of the court features treasure chests and ruins in a desert setting, and the music that plays is an arrangement of "Out of the Woods", the overworld theme of Wario Land 3. On the ground of the court, there is the picture of Wario holding his racket. This court has a weak bounce with a slow ball speed. To unlock the court, the player has to win the third round of Treasure Box, a minigame in Mario Tennis for the Game Boy Color, then transfer the data through a Transfer Pak. Due to the Transfer Pak being not compatible with the Wii, Wii U or Nintendo Switch, this court cannot be legitimately unlocked in the Virtual Console versions of the game.
