'''{{world|4|ghost}}''' is the [[Ghost House]] of [[World 4 (New Super Mario Bros. Wii)|World 4]] in ''[[New Super Mario Bros. Wii]]''. Completing this level through the normal goal unlocks [[World 4-5 (New Super Mario Bros. Wii)|World 4-5]], while finding the hidden goal unlocks a shortcut to {{world-link|4|castle|World 4-Castle (New Super Mario Bros. Wii)}}.

==Layout==
In this level, at the start, the floor moves up or down when the player stands on it. At the left side of the beginning of the level, a [[Super Star|Star]] can be found. Enemies found here include [[Boo]]s and [[Scaredy Rat]]s. The player must then hit a [[P Switch]] on the ceiling in a hidden alcove which requires standing on the floor which moves up. This enables access to the door leading to the next area. Through this door is a long area of stairways going up and done, where many clusters of Scaredy Rats run along. Near the beginning of the section, a hidden [[barrel]] can be found in a section of the ceiling. Past the area is the [[Goal Pole|pole]]. 

==[[Star Coin]]s==
*'''Star Coin 1''': The first Star Coin is hidden behind the platform to the right of the first [[Scaredy Rat]]. Mario and co. should stand on it to make it descend and reveal the Star Coin.
*'''Star Coin 2''': The second Star Coin is in a hidden area, in the wall to the right of the stairs-like platforms with many Mousers. Mario and co. should run into the wall, jump up, and continue left to get the Star Coin.
*'''Star Coin 3''': Mario and co. must follow the path to the secret exit. About halfway from the entrance to the exit of the secret room, the third Star Coin is floating to the high-left of a phony [[Warp Door]]. Mario and co. must get on the platform directly below it, wait for it to ascend high enough, then jump to the Star Coin, all while avoiding the nearby [[Boo]]s. Mario and co. can also jump to the Star Coin from the aforementioned phony Warp Door.

==Hidden goal==
*Before the door to the second area, there is a [[? Block]] containing a coin (or a mushroom if the player is Small Mario). The player should stand on the platform below it to reveal a hidden door. They should then go to the door to the next area and continue to the [[Goal Pole (secret)|hidden goal]]. This exit unlocks {{world-link|4|castle|World 4-Castle (New Super Mario Bros. Wii)}} and a Yellow [[Toad House]].
