Booster Tower

Booster Tower is a tower of amusement belonging to Booster and his Snifits. When Princess Toadstool falls here from the sky, Booster wants to marry her, but Mario saves her.

The building itself is filled with many dangerous traps and wacky enemies. However, the music is strangely soothing. Booster is often seen riding a miniature train throughout the tower.

At the entrance of the tower, Mario meets Bowser. With no troops left, he declares Mario, Mallow and Geno members of the Koopa Troop, thus joining Mario's party.

The tower is also the home to Knife Guy and Grate Guy.
