How to clear Vanilla Ghost House in Super Mario World for the Super Nintendo Entertainment System and Game Boy Advance.

How to Clear Vanilla Ghost House
Go to the right and crouch or jump over the Eerie if you're tall. Then you find some Circling Boo Buddies. Go through the gap in the circle to to reach the Prize Block at the top, which contains a Fire Flower. Then go back out of the circle, then go back through the gap and get the Dragon Coin.
Go through the gap in the circle (watch out for the Eeries on the left if you go through the left), and when you go to the right, you will find several platforms and several Boos. There is a hidden 1-Up that you can get here. To get them, jump on the platforms in the following order:
___ ___ _1_ ___ _3_ ___ _2_ _4_
Go to the right and get the Dragon Coin on top of the upper platform.
Then go to the right and you find a lot of Blocks, with a Big Boo on the right side. There is a Block in the bottom-right row that you can hit to make a Beanstalk appear. The Block is below the space between the two upper-right platforms. Lure the Big Boo to the left so you can hit that block and make the Beanstalk appear. Before you climb it, if you want a Cape Feather, go to the right and hit the Prize Block (which has another Big Boo to the right) to get the Cape Feather. Then go back to the left and climb up the Beanstalk.
Go to the right and get the four coins and Dragon Coin, then jump over the gap and get the coins on the right, dodging the Eeries that float past.
Fall down below and get the three coins as you fall. There is a Boo below you, so make sure not to fall on it. Go to the left through the gap in the Circling Boo Buddies, then quickly hit the Prize Block repeatedly to get as many coins as you can before it turns into a Brown Block. Then jump on top of the Brown Block to get the Dragon Coin. Go through the gap in the circle and go through the door on the right.
Throughout this area, there are Big Bubbles that float past. You can't stomp on them, but you can bounce off of them if you use a Spin Jump.
Go to the right and collect the coins on the way, then when you reach some Blocks, hit the middle one to get a P Switch, but don't step on it yet. Pick it up and take it to the right. Ignore the door, because it just sends you back to an earlier part of the Ghost House. Instead, go to the right, get the Dragon Coin, and collect the coins in the shape of a door, then step on the P Switch and go through the Blue Door that appears. Go to the right and go through the Giant Gate to complete the level.
After the Level
The path to the east unlocks, and you can go to Vanilla Dome 3.
