World Bowser is the eighth and final overworld of Super Mario 3D World. It is a large amusement park built in the likeness of Bowser. There is a volcano in the back, and it sits high above the main map. It contains eight standard courses, two Boss Arenas, a Mystery House, a Toad House, and Bowser's Castle. The world is powered by the Sprixie Princesses, who are liberated when the world is completed.
