The Great Tower of Bowser Land

The Great Tower of Bowser Land or World Bowser-Castle is the final standard course of World Bowser, and the final story course in Super Mario 3D World. It is set in Bowser's Castle, now amusement-park themed, with a very tall tower on the center.

Layout
The course begins near the remains of the Bowser Mobile and right next to it a zipline. The course contains Bottomless Pits, Fireballs raining from the sky, along with Spikes in the floor.

Near the end of the course, Bowser appears and uses a Super Bell to turn himself into Meowser. The rest of the course involves climbing a large tower while Meowser shoots fireballs, scratches through the wall, and uses Double Cherries so his doubles can assist. At the end of the course, a large POW Block must be hit multiple times to defeat Meowser.

A Warp Box to the Goal Pole reveals itself, and the course ends with all seven Sprixie Princesses rescued.

During the credits, Mario, Luigi, Peach and Blue Toad return to the Mushroom Kingdom, as do the other Toads. Bowser is trapped inside a bottle, Boom Boom is upset and Pom Pom tries to comfort him.
