This is the fourth and final course of special cup and final course of the Nitro grand prix. This is the hardest course in the game and may take time to master it. This track or similar tracks have appeared in every Mario Kart game made.
The big and only hazard of the course is the edge of track because there is no border on most of the track. Also watch out for bananas or being hit by shells while speeding upside down on the rainbow part of the track, for this may cause you to fall upside down and have to get saved by Lakitu
There are no shortcuts for this track.
One tip is to try to stay in the middle of the track to avoid falling off. Also try to hit all the power boost in the beginning of track near the first turn. Finally power slide on most of the turn to get a boost
