The level has five Advance Coins. The key art featured Ludwig von Koopa.

Layout
The area is a sky-based level. Mario starts on some clouds, and must cross several motion platforms to reach another cloud platform. On this platform is a single red Koopa Troopa. After this, there are Snake Blocks, with some Koopa Paratroopas along the path. Afterward is another cloud platform, with two Seesaws that shift with Mario's weight leading to more Snake Blocks. After taking the Snake Blocks, there are two Brick Block towers, with a Pile Driver Micro-Goomba. The Warp Pipe takes the player to another Warp Pipe leading to the next room of the fortress.

This part of the fortress is a warp-around area. It is filled with solid, unbreakable blocks and spikes, but there are fast-moving lift platforms to help maneuver through them. At the bottom is a Warp Pipe leading to the next room.

The room is mostly straightforward to a pipe leading to the end. The only things in the room are Boos and a line-guided platform. However, by going down the hole created by stepping on the platform, which flies up and down off the screen, there is a pipe. This pipe leads to an underground area with several coins, and two doors, one higher up and one at the very bottom, both leading to different parts of the same room.

The upper door takes the player to an area with a red Koopa Troopa necessary to break several Brick Blocks to reach a lower part of the room. From there, the player needs to jump over the unbreakable blocks to reach a Warp Pipe leading to the end of the level. The bottom door leads to the Warp Pipe.

The end of the level has several Brick Blocks containing coins. The player must simply head over to the end.
