World 5-Ghost House (New Super Mario Bros. Wii)

 is the Ghost House of World 5 in New Super Mario Bros. Wii. It is the third Ghost House in the game.

Layout
Common Ghost House enemies can be found, including Boos. More of a maze than a typical ghost house, this house has a multitude of doors in each room; with some paths instead leading to dead ends. Since most of the doors are either fake or go in circles, there is only one successful path. To add to the difficulty, it is a very dark level.

To get to the path that leads to the exit, Mario and co. must fall into the first gap, jump across the second and third gaps, fall into the fourth gap, and jump across the fifth gap.

There is a secret exit in this level that takes Mario and company to the Warp Cannon, which shoots Mario and co. to World 8.

Star Coins

 * Star Coin 1: At the first split path, Mario and co. should take the Warp Door on top. Once there, Mario and co. should then run all the way to the right, jump on top of the platform, walk into the wall, and a hidden area with the first Star Coin will be revealed.
 * Star Coin 2: As opposed to taking the top Warp Door at the first split path, Mario and co. should fall to the bottom path and take the lower Warp Door. Once in the new area, the second Star Coin is floating to the right of the Warp Door that exits from this area. Mario and co. should jump to it, then wall kick back to safety.
 * Star Coin 3: Mario and co. should run past the first two Warp Doors and continue ahead to the second Warp Door after the Coin-filled stairs. Once there, the third Star Coin will be floating above the second wheel of Circling Boo Buddies. After getting on the platform that the Boo Buddies surround, Mario and co. should wait for the gap in the Boo Buddy wheel to be adjacent with the Star Coin, then jump up to it.

Secret Exit
To get to the secret exit, Mario and co. must fall into the first gap, jump across the second and third gaps, and finally, fall into the fourth and fifth gaps, where they must go through a hidden passage to the left-most door. After making it past the room, they will reach the secret exit, with only a lone Boo and a group of Circling Boo Buddies standing in their way.
