The stage is in the shape of an enormous doughnut as the name implies, and in the middle there is a large hole full of lava. If a player falls into it, they will lose a balloon and will have to be returned by a Lakitu. There are four block towers located around the course that provide a means of evasion from opposing racers and their items. The course is also slightly sloped inwards.
