N64 Big Donut

Big Donut is a battle course in Mario Kart 64. As its name implies, the course is in the shape of a large donut. In the center hole of the donut is a pool of lava. If the players fall in it, they lose a balloon, and a Lakitu brings them out. There are also four block towers located around the course that provide a means to evade opposing racers and their items. The course is also slightly sloped inwards.
