World 7-Airship (Super Mario 3D Land)
From the Super Mario Wiki
The level starts on an airship. The player must then cross a rotating platform to reach another airship segment, then must cross two more to reach another segment. Following this is a series of rotating platforms, with a Magikoopa appearing to attack the player. Another airship segment and several more rotating platforms are after this. On these rotating platforms are spikes and wooden cutout Goombas, as well as Magikoopas. On the airship after this is a Warp Pipe guarded by two Rocky Wrenches; one throws wrenches, and the other, who is in the pipe, throws Bob-ombs. Down the pipe is the boss room, which contains both Boom Boom and Pom Pom (with Boom Boom's boss theme used). The pipe that appears after defeating them leads the player to an airship with a green + Clock and the flagpole.
