The Great Tower of Bowser Land

The Great Tower of Bowser Land (known as The Great Tower of Bowser World in Europe and Australia), also known as  is the final standard course of World Bowser, and the final main 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. Unlocking this level requires 170 Green Stars.

Layout
The course begins near the remains of the Bowser Mobile and right next to it a zipline. If the players have a cat suit, scratching the golden tire wheel will make the car light up and make a foghorn noise. Then after jumping onto the zipline and jumping off, the remainder of the course is on the roof. The course contains Bottomless Pits, Volcanic Debris from the volcano in the background, along with Spikes in the floor. After passing that, the Crazy Clown Ferris Wheel, Captain Toad awaits the players before them get on another zipline that leads to Bowser.

After that, 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 four times to defeat Meowser.

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

During the credits, Mario, Luigi, Peach, and Toad return to the Mushroom Kingdom, as do the other Toad Brigade members. Bowser is trapped inside a bottle, Boom Boom is upset and Pom Pom tries to comfort him. The Sprixie Princesses also give their new friends a fond farewell.
