The House of Stairs (or World 5-Ghost) is the Ghost House and the fifth level of Moonview Glacier in Newer Super Mario Bros. DS. This is the only level in the game to have a secret boss. This boss is King Boo, and defeating him will unlock World 5-Cannon, which is the only way to get to Lunar Realm.

Layout

This level features multiple switches that reveal stairs. Boos are also scattered throughout the level. Red blocks also appear in the level, also activated via switches.

After the checkpoint area, you will need to activate all three switches. Once activating the ? Switch in a hidden block, stairs will appear. If you did not activate all the switches, you will need to enter the door that will lead you back to the top of the area. In the last room, there are some blocks that activate the stairs. After this room, you will enter the room with the goal pole.

Secret Exit

To reach this secret exit, you need to first activate the bottom ? Switch. Head up the stairs and press the red ! Switch and then enter the door that was hovering in the air. It then leads to a boss battle against King Boo.

Trivia

  • The boss addition was a very late addition, as the door leading to the secret exit initially only went to the secret flag pole. The removed room still exists in the game code.
