How to clear Donut Plains 2 in Super Mario World for the Super Nintendo Entertainment System and Game Boy Advance.

How to Clear Donut Plains 2
This level automatically scrolls from right to left.
Go to the right and there are three Prize Blocks. The middle Prize Block contains many coins, so hit it as quickly as you can to get as many coins from it as possible before it turns into a Brown Block. If you visited the Yellow Switch Palace, there is a Yellow Block at the end, which contains a Super Mushroom.
There is a Buzzy Beetle after that, and a Swooper bat that swoops down from the ceiling, and then another Buzzy Beetle and Swooper.
Next, there is a yellow Sand Tide with a Buzzy Beetle on it. The Sand Tide moves up and down, but this one won't crush you, so wait for it to move up far enough to let you get get the four coins and Dragon Coin up above.
After the Sand Tide goes back down, go to the right. There is a Swooper, and a Prize Block that contains a Cape Feather. Then there is a Sand Tide that slides down and can crush you, so if it goes down to the ground while you're on the left side, wait for it to go back up before you go past. There is a Prize Block after the Sand Tide that contains many coins, so hit it as quickly as you can to get as many coins from it as possible before it turns into a Brown Block.
Next, there are Sand Tides that go up and down. The first Sand Tide has a Buzzy Beetle on it. Throughout this area, there are several Swoopers. If you want to go to the secret exit, you can go up the pipe that is above the flat Sand Tide. If you don't want to go to the secret exit, skip ahead to Giant Gate Path on this page.
Secret Exit Path
If you go up the pipe, you reach an area that doesn't automatically scroll. There will be a Yellow Block or yellow Dotted Line Block. After a hole in the floor, there is a Passin' Chuck that keeps kicking gridiron footballs that bounce randomly.
To the right, there are two ledges, followed by some Blocks. The rightmost Block will grow a Beanstalk if you hit it. If you're Caped Mario, you can press X or Y to do a spin attack and hit the Block, or just fly up and hit it. Or, if you have Yoshi, you can go do the right, press A to do a Spin Jump and break the Blocks above the shell, then have Yoshi eat the shell. Blue shells make Yoshi grow wings, so you can fly up above the uppermost Block to the left of where you got the blue shell.
Whether you climb the beanstalk or fly with Yoshi, you will reach a small room with a key and a keyhole. Hold X or Y to pick up the key, then use it on the keyhole to go through the secret exit. This ends the level, and a path to the west will unlock, and you can go to the Green Switch Palace.
Giant Gate Path
If you decided not to go up the pipe mentioned earlier, then go to the right and get the Dragon Coin between the Sand Tides.
Next, there are Swoopers and Buzzy Beetles, as well as three coins, a Dragon Coin, and another three coins.
Then there is a Sand Tide that comes down from the ceiling. There is a Flying Prize Block beneath this Sand Tide that contains a Cape Feather. There are three Buzzy Beetles beneath the Sand Tide.
After that, there is eventually a gap to jump over, with a Dragon Coin above it. Don't jump onto the wall, because it goes all the way to the ceiling, so you will get crushed if you stay on it. After the wall goes back down, jump onto it, then stand on the right side, then when you can see the coins and Dragon Coin on the right, jump to get the coins.
Then go to the right, where there is a pipe, followed by two Spike Tops, which can walk up walls. After that, go through the pipe on the right.
Then go to the right and go through the Giant Gate to complete the level.
After the Level
If you used the secret exit, the west path will unlock and you can go to the Green Switch Palace. If you used the Giant Gate to complete the level, the north path will unlock and you can go to Donut Ghost House.
