Layout
As stated above, the level begins in Boom Boom's area at the end of the previous level. The player must hit several invisible Question Blocks at the other end of the room to reach a Warp Pipe leading to the upper deck, which automatically scrolls. The player must avoid the projectiles of cannons and several Rocky Wrenches while navigating the airship. At the end of this is a second Warp Pipe.

Down the pipe is a room with two Boomerang Bros.. The pipe after this leads to another airship segment. However, this area mostly consists of Rocket Engines. At one point, there are three Fire Bros., and near the end there are a pair of Bill Blasters. At this point, the rest of the airship stops automatically scrolling, allowing Mario to move at his own pace. Before the Warp Pipe here is a Question Block with a Super Leaf.

The pipe leads to a chamber with Bowser inside. He is defeated in the same manner as the previous battles. However, present in the room are several blocks that he cannot destroy with his ground pound move.
