Donut Secret House

Donut Secret House is a secret Ghost House in the game Super Mario World. It can be accessed by completing the secret exit of Donut Secret 1. This level also has a secret exit. This level is the home of The Big Boo, the miniboss who protects the Star Road. If the Mario Bros. beat this boss, they'll have access to the Star World.

Overview
This level consists of two main rooms, a boss room, and a hallway used to reset the second room which the player has 400 seconds on the Timer to clear. This level contains no Dragon Coins.

In the first room, the player will have to avoid 10 Boo Buddies floating in circles. After the Boo Buddies, the player will encounter an Eerie and a Big Blue Boo. If the player activates the P-Switch, the Used Block will turn into a Coin, and the spring that was on top of it will fall down, allowing the player to jump over the big boo easily. There is then a series of staircases for about 10 seconds. Just before the player reaches the end of the first room, a platform underneath the last staircase is visible with a dragon coin and a ? block however the staircase refines the player from entering the platform at this stage and can only be entered later on.

The second room consists of more Boo Buddies moving in a circular motion, and some that will chase Mario or Luigi. At the beginning of the room the player can find a ? Block that contains a Mushroom if small, or Fire Flower if large. When at the end of the room, in the Super Mario World 2:Super Mario Advance version, a series of identical ledges can be seen on the left wall which lead up to a dragon coin. Below them is the usual standard door seen in many other ghost houses which take the player back towards the beginning of the level (at the first boo buddies floating in circles in the first room). Nearby is the usual main exit leading to the Giant Gate, which like many other ghost houses has coins surrounding the door. The player must collect the coins and once the P-Switch is activated, the blue standard exit door will appear without any blocks. There is also another door which is visible both before and after the P-Switch is pressed, it is in midair surrounded by yellow blocks. Activating the P-Switch will create new blocks for the player to stand on to enter the door. This door takes the player to the hall with many Boo buddies and Eeries. There is a coin trail from a ? block in here and also one door on the far right and one on the far left. The door on the right takes the player back to the start of the second room and the one on the left takes the player to that platform with the ? block at the end of the first room mentioned earlier. The fifth door and second exit of the ghost house is located at the end of the second room, where the player must activate the P-Switch and go to the door in mid air as though the player but then jump up and hit the above block which is a vine. Up the vine is the final blue door (which disappears once the P-Switch time is over). In the GBA version, there is also a dragon coin up there.

Exits
The door to the normal exit can be found in the second room. To access it, the player should collect the 5 coins that make the outline of a door about halfway through. Then, the player will need to carry the P-Switch back to this spot and stomp it, making a door appear. The Giant Gate can be found through this door, and leads to Donut Secret 2.

The door to the secret exit can be found in the second room as well. To access it, the player should carry the P-Switch to the area with the door floating near Turning Blocks, activate it, and then hit the middle Turning Block to make a vine go up to a hidden ledge. The secret exit door is up there. An alternate strategy to this is to fly up there with Cape Mario. Inside this door is a mini-boss, the translucent white The Big Boo which will fly around in a pattern. To defeat it, the player will need to throw Grab Blocks at it three times. The boss itself is completely harmless, only the two normal Boos are dangerous. The player can use the Star Road this activates to go to Star World 1.
