Donut Ghost House

Donut Ghost House is the first of two Ghost Houses in the Donut Plains, and also the first ever Ghost House Mario or Luigi will visit in the game Super Mario World. The level introduces Boos to the game. It also has a secret exit to the Top Secret Area.

Overview
It is a short level; however, the player has to use the right tactics in order to finish it. The Ghost House basically consists of three rooms. In the first one, Mario or Luigi will just need to move forward and avoid the Boos and the abysses.

In the second room, the player will have no other choice than to use the Door on the right side (unless he or she has a Cape, in which case he or she may simply fly to the exit door in the top left corner). When entering, Mario or Luigi will find himself in the very same room again, but this time in a different location. Now he can choose between taking the same Door again, which actually leads to the third room this time, or to hit the Block above which will release a P-Switch. When hitting the Block, an arrow made of Coins will guide the way to another Door. When entering, Mario comes into a small room with a single ? Block. The block, when hit, releases a Coin Snake. If the player leaves the room, he will not reach the third room, but the second again. This means that if not ignoring the P-Switch at least once, the player will never reach the exit of the level.

The third room looks exactly like the second one. However, the Block this time does not release a P-Switch but a Beanstalk, allowing the player to climb up to the exit door. When being in the third room and taking the Door on the right side again, the player will once again appear in the second room.

Exits
The above-mentioned regular exit, when used, makes a bridge appear that crosses the river in the East, allowing Mario or Luigi to go to Donut Plains 3.

There is another exit in the game. Using it requires Mario or Luigi to enter the Ghost House as Cape Mario or Cape Luigi, respectively. In the first room, the player may move forward until they reach the first abyss. When now flying to the left, he or she will reach a secret platform that guides the player to four Blocks and a Door. All the Blocks contain 1-Up Mushrooms, and the Door leads to the secret exit with a Giant Gate. When used, a new way will open northwards that leads to the Top Secret Area.
