World Bowser

World Bowser (alternatively called Bowser World or Bowser Land, as implied by the name of the world's final level) is the eighth and final story world of Super Mario 3D World. Unlike most endgame Mario worlds (including World Castle, which came immediately before it), World Bowser is not a volcanic stage; rather, it is a large amusement park built in the likeness of Bowser, with a volcano in the back, and it sits high above every preceding world.

It contains eight standard courses, two Boss Arenas, a Mystery House, a Toad House, a Sprixie House, and Bowser's Castle; it is also the only normal world without an Enemy Battle. The world is apparently powered by the Sprixie Princesses, who are freed upon the completion of the world's Castle. The bosses encountered here are Pom Pom, Motley Bossblob, Hisstocrat, and the final boss, Meowser.

Trivia

 * There is a glitch where the player can get on top of the pipe leading to this world; if the player falls off the pipe, they will land in World 3.
 * In Mario Party 10, many of the Bowser Party minigames appear to take place in World Bowser or a similarly-designed area.
