Valley Ghost House

The Valley Ghost House is the Ghost House of the Valley of Bowser in Super Mario World. It is notable for a coin dash when the Switch Block is on.

Layout
From the first room, the player is near groups of six coins each, along with some Big Bubbles. When the player reaches the next room (or the main room), there is a Switch Block on top of the door. The player can run either to the right or to the left. On the way, the player encounters Boo Buddies and Eeries. If the player heads to the left, there is a door that leads them to another room, with two Boo Buddies, a coin trailer, and a Dragon Coin, as well as a door that takes them back to the main room. However, if the player heads to the right, there are five doors, along with many coins if the Switch Block is still active.
 * The first door leads Mario (or Luigi) back to the first room.
 * The second door leads Mario to the same place as the door on the very left of the main room.
 * The third and fourth doors lead to the Giant Gate, thus heading to Valley of Bowser 3.
 * The fifth door leads to a room with a Switch Block, a Dragon Coin, and some other coins.

On the right side of the fifth door of the main room, there is a 1-Up Mushroom.

Secret exit
In the second room of the level, where the player starts on a platform with a Switch Block above, the player must activate the switch and move as quickly as possible to the last door on the right. In the next room, the player must take the Switch Block to the right area, activate the Control Coin, and make the coins head up to the right. When the Switch Block is pressed, the player must enter a small secret space leading to a key and a keyhole by being small or by sliding and ducking. It is also possible to fly up there with a Cape Feather and then duck to enter the small space. Putting the key into the keyhole leads the player straight to #7 Larry's Castle.
