N64 Kalimari Desert

Kalimari Desert is a race course in Mario Kart 64. The course's most notable feature is the train track that goes through a mountain. The train constantly moves around the track, often crossing through the racers' path. Depending on what mode is being played, the train may or may not have coaches attached to it. Despite its name, there are no squid, just lots of cacti. The course contains a small shortcut that can be done by using a mushroom to jump over the track.
