""Wario Colosseum is a twisting, turning, spiraling maze of steel and concrete. If you can survive two laps of the massive dash-panel jumps and the numerous sick curves, you‘re ready for the big time.""

In Wario Colosseum, just like someone would think, the background shows that you are racing inside of a giant colosseum. The race takes place at nighttime, while Waluigi Stadium takes place more at evening time, when the sun is setting. The course is very long, so there are two laps, instead of the regular amount of three. When going off ramps, most of them have a ring of fireballs. If the player accidentally hits them and doesn't go through them, the character will spin out and most likely fall. These rings of fireballs also appear in Waluigi Stadium. This course's roads are very high up and are not touching the ground at all. It is the longest track in the game.
