|A four-player race in Mushroom City.|
|First appearance||Mario Kart: Double Dash!! (2003)|
|Appearances||Mario Kart: Double Dash!!|
This is one of the most confusing tracks in the game due of its many intersections. The course is dangerous because cars drive around, and if racers hit one, they slip. Also, racers shouldn't hit the Wiggler buses, because they will flip the karts. There are Bob-omb Cars that drive around, and whenever one is hit by an item or a racer, the Bob-omb Car will blow up, and the racer will go flying, leaving the thrower dragging in the back. Players will lose any item that they had before they collided with the Bob-omb Car. There are red and blue cars, and Mushroom Cars, but no regular buses like there are in Mushroom Bridge. If a Mushroom Car is hit though, the racer will be stopped cold, but will not take damage. The Mushroom car will throw out a Mushroom, and if hit, the racer will get a decent amount of boost. The music in this course is the same as in Mushroom Bridge.
After the first branching path off the right of the main road near the beginning of the track, stay close to the right wall. A purple-shaded alleyway is there that twists in an S-curve. An item box is present at the end of the alleyway.
- Rainbow Road is above this track in single player mode. However, it is absent in multiplayer mode.
