World 6-Ghost House (New Super Mario Bros. 2)

This Ghost House is a difficult maze, similar to the Ghost House found in World 5 in New Super Mario Bros. Wii. Mario must press the P-Switch at the end of the room and go in the right door. Then, the player must head right until they see a door. Mario should go inside. What looks like the same room is actually different, as the Big Boo has 'turned into' a Boo. Mario must then press the P-Switch and head left. When Mario gets to the first part of the room, he should lure away the Boo from its position, and press the P-Switch that it was hiding. Some stairs will then be visible, and Mario must climb them. At the top is a door that Mario must enter. Then the player will be in a room with the first Star Coin (see below). Mario should not enter the door located on the bottom of the room. He should instead wait and head back up for a block that has a P-Switch on it, on the left side. When it is pressed, a path is made to the exit door.

Star Coins

 * Star Coin 1: At the end of the first room, the player must hit the ? Switch. They should then fall down, head right, hit the Brick Block and press another ? Switch. Up ahead is the first coin.
 * Star Coin 2: In the third area, The player must continue left and find a ? switch to reveal the path to the second star coin.
 * Star Coin 3: In the second area (After leaving the third area), the player should continue to the right and find a ? switch to reveal a hidden door that leads to the third star coin.

Secret Exit
After the player hits the ? Switch in the room that slides opens the ceiling leading to a star coin, they must wall jump up to the star coin, but instead of heading back down, keep wall jumping for about 3 screens and they will come to a door leading to the secret exit. The Secret Exit unlocks World 6-A.
