The stage is made completely out of wooden planks in the shape of a circle, and they slope a little to the center. This gives the Course a donut shape in appearance, in accordance with its name. In the epicenter of the course, a giant pit of lava awaits those who venture to close to the middle (donut hole). 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.
