There is a secret exit in the Donut Plains Ghost House, but I can't find..

You need a cape for this. When you enter fly to the top left corner and run along the new path.

You need to get a cape (I got one and held one at the top of the screen you should too). Run and fly up to the top left try not to hit the boos when you fly up (if you do hit a boo press select to get the item your holding up at the top if your holding one) when you make it (if you do) keep running to the right when you come to a room you'll see a couple of blocks hit them (from the bottom of course) lives will come out of the blocks then go through the door (by getting right in front of it and pressing up) and there's the exit!!!!!!!!!!!!!! When you do the secret you'll get something real cool (no bad guys what so ever) where there is four power power ups and a yoshi egg (you never know what color yoshi you'll get) can someone please answer my question i'm VideoGameMaster I know every secret in the whole game except the level in my question Thanks!!!!!!!!!!!!!!!!!

Pretty much all you need is a feather and then run and jump up but keep all the way to the left. Like fly up on the left side of the level and there is a platform up there.
