World 7-Ghost House (New Super Mario Bros. Wii)

 is the last Ghost House in New Super Mario Bros. Wii is the only one to feature Broozers (which are mostly placed near barrels). Crowbers also appear outside the Ghost House near the end of the level. There is also a secret exit in this course.

Enemies

 * Broozers
 * Boos
 * Big Boos
 * Crowbers
 * Ghost Blocks

Star Coins

 * Star Coin 1: The first Star Coin is right at the beginning of the level and blocked off by three blocks. Mario and co. must lead the nearby Broozer to the blocks to break them and make the Star Coin accessible.
 * Star Coin 2: Once reaching the area with five Warp Doors, Mario and co. must enter the one on the top-right. Once there, Mario and co. should lure the Big Boo away from its starting position to access the second Star Coin.
 * Star Coin 3: Mario and co. must follow the path to the secret exit. When reaching the final area with the Red Flagpole, instead of finishing the level, Mario and co. should go through the other Warp Door, on the ground. The third Star Coin is then floating in the middle of the room. To obtain it, Mario and co. must activate the ? Switch all the way to the right to summon a floating platform, and jump from it.

Secret Exit
About midway through the first area, there is a Broozer and a barrel on top of some wood with a crack on it on the left wall. The Broozer should be on the side of the cracked wood and then break some hidden blocks in order to enter a hidden door behind the blocks.
