The Great Tower of Bowser Land
Template:Levelbox
The Great Tower of Bowser Land (known as The Great Tower of Bowser World in the British English version), also known as World 
Bowser-
Castle is the final standard course of World Bowser, and the final main course in Super Mario 3D World. It is set in an amusement-park themed Bowser's Castle, with a very tall tower in the center. Unlocking this level requires 170 Green Stars.
Layout
The course begins near the remains of the Koopa Chase Lv2, with a zipline right next to it; scratching the car while wearing a Cat Suit will cause it to light up while the horn blares. The zipline leads onto a rooftop with obstacles that include bottomless pits, debris from the volcano in the background, and spikes in the floor. Upon reaching the Crazy Clown Ferris Wheel, Captain Toad greets the player(s) as he stands next to another zipline.
Once the player(s) reach the large tower in the center, Bowser appears and uses a Super Bell to turn himself into Meowser. The rest of the course involves climbing the tower while Meowser attacks them repeatedly; he shoots fireballs, climbs up walls and slides down them, and often breaks through them with his scratches. Eventually, he uses Double Cherries so his doubles can assist him. At the end of the course, a giant Super POW Block must be hit four times to finally defeat Meowser.
Upon defeating him, 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 Captain Toad and the other Toads. Bowser is left trapped inside a bottle, while Boom Boom is upset and Pom Pom tries to comfort him. The Sprixie Princesses, their people and Plessie also give their new friends a fond farewell. Additionally, Rosalina appears if the player replays the level after unlocking her.
Green Stars
- Green Star 1: After getting off of the first zipline, the Green Star is on the rightmost side of the highest part of the first building the player lands on.
- Green Star 2: On the Ferris Wheel, the four Bullies must be knocked off the platforms to reveal the second Green Star. If all the Bullies are knocked off, the Green Star will reveal in the center of the Ferris Wheel.
- Green Star 3: During the first phase of the final battle, revealed after collecting every Green Coin from the Green Star Ring.
Stamp
- At the end of the stage, near the Goal Pole, there is a bell tree with the stamp floating directly above it. The stamp is of Meowser.
