The Great Tower of Bowser Land

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

Layout
Mario starts on a stage where the wrecked Bowser car is, and right next to it a zipline. It takes him to a tower with purple and green lights on the floor, where some fireballs fall from the sky. Mario, then, finds a Clear Pipe cannon that launches him to another tower with a few Cat Goombas on a ramp and, next to it, there is a small ferris wheel with Koopa Clown Car's face on the center and one Bully on each of the four platforms. Captain Toad is found on another tower to the right, near another zipline. Traveling on it, Bowser's immense tower can be seen on the background. Mario is taken to another stage and a bridge during rain, leading to the start of the tower.

Before Mario can reach it, Bowser appears and uses a Super Bell to turn himself into the tiger-like Cat Bowser. Mario starts to climb the tower using platforms and Clear Pipes, while Cat Bowser climbs the walls trying to attack the plumber. Bowser jumps on a platform right under a POW Block. Mario hits it and Bowser is sent flying. A Clear Pipe cannon appears, so Mario uses it to rise further on the building. Suddenly, Cat Bowser reappears and climbs the wall frenetically, chasing Mario as he travels through the pipe. He, then, creates clones that jump into the next part of the tower. Mario jumps on some platforms while the clones break the walls and try to attack him with their claws and tails. The next part has a set of stairs that Mario can climb to reach the top, where the real Cat Bowser is on top of a giant POW Block, holding a bottle with all the Sprixies trapped inside it. The clones reach the top and surround Mario. But he, then, hits the block until Bowser drops the bottle freeing the Sprixies and is sent flying again. The Sprixies build a Clear Pipe that goes to a tower with the Goal Pole.

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.
