Bowser's Last Stand

Kakushi Kuppa Jō (かくしクッパじょう Hidden Bowser's Castle) is an e-Reader level for Super Mario Advance 4: Super Mario Bros. 3. The level contains five Advance Coins.

Level Synopsis
This level takes place within a False Bowser's castle. Its entrance room contains some Gray Bowser Statues and a short lava pool with two Lava Bubbles. A Hot Foot and a Door are found at the end of this room. The door takes Mario to a vertical area divided into three sections. Mario must choose one of them and drop its Donut Lift to enter the corresponding door.


 * Left door: a room guarded by Boomerang Bros., Hammer Bros., Fire Bros. and a Sledge Bro.. The Hammer Bros. hide an Advance Coin.
 * Middle Door: a corridor over lava filled with Lava Bubbles. An Advance Coin is found above a moving platform.
 * Right door: a lava pool with jumping Cheep-Cheeps. There is an Advance Coin after the platform rails.

They all contain a Warp Pipe that takes Mario to a longer corridor, where Hot Foots, Bony Beetles and Dry Bones are found. Upward Donut Lifts appear here as well, and can be used to collect another Advance Coin.

The next area is constantly attacked attacked by Magikoopas. An Advance Coin is stuck inside a Brick Block cage, which Magikoopa can destroy (Mario can get it using a boomerang too). After that, Mario faces fire-breathing Gray Bowser Statues and Gold Bowser Statues on falling spike platforms. There is another Advance Coin before the door.

The next room features False Bowser's incoming Fireballs. The upper route is made of falling platforms and has the double of Fireballs. However, Mario can get an Advance Coin inside the False Bowser room. The lower route is made of stationary blocks, has Lava Bubbles and a few fireballs, but the player can't have the special coin fighting with False Bowser via the lower door.
