The Racetrack is a typical Mario Kart Racetrack. Although it hasn't been officially confirmed by Alvin-Earthworm, it is likely to be Mario Circuit.
The track seems to have a grandstand surrounding one side throughout the entire track (however it cannot be seen from a top-down perspective), which curiously houses a number of Kirby enemies.
The Lakitu Bros. are the commentators, or at least commentate sometimes.
During the match the track gets covered in a few flames and scorch marks, due to the aggressive nature of the racers, and at the very end suffers a large explosion thanks to Bowser's Bob-Ombs and the "I Like Cereal!" banana.
