World 6 (Paper Mario: Sticker Star)

World 6 is the sixth and final world found in Paper Mario: Sticker Star. Unlike the other five worlds, this world does not have any distinct theme, as the three levels (making it the shortest world in the game) take place at a rock formation out at sea, an airship, and Bowser's Castle. Additionally, only the Gate Cliff may be accessed with the boat; to reach the other two levels of the world requires the assistance of Flutter. Rocky Wrenches make their debut in 6-2, and Hammer Bros. and their sub-species are common enemies. Bowser Jr. and Kamek are also fought for the final time. The world's boss is Bowser, making him the final boss in the game.
