How to clear Donut Plains 3 in Super Mario World for the Super Nintendo Entertainment System and Game Boy Advance.

How to Clear Donut Plains 3
If you get at least 30 coins before a certain point in this level, you can get a 1-Up. The count is NOT based on how many coins are displayed in the upper-right of the screen, so there is no need to stop collecting coins if it says 99 in the upper-right corner.
Go to the right and jump on one of the three platforms of the Triple Swing Lift. Jump from there to the Mushroom Platform on the right. If you have been to the Green Switch Palace, there will be a Green Block that you can hit to get a Cape Feather. Then fall down to the right to reach a Mushroom Platform with two coins.
Next, there is a Pulley Lift going around a track, followed by another Triple Swing Lift. Jump onto the Triple Swing Lift and get the Dragon Coin at the top, then jump onto the Mushroom Platform on the right.
There is a blue Koopa Troopa and four coins above it. If Yoshi eats the blue Koopa Troopa, he can fly. If you fly up and to the right, you find clouds in the sky with many coins and a Dragon Coin above them. Be sure to get the two coins beyond the edge of the clouds, and fall straight down from there. Skip ahead to Find a Message Block on this page.
If you don't have Yoshi, go to the right from the blue Koopa Troopa's platform, and you will find green Koopa Paratroopas and two Prize Blocks. The first Paratroopa bounces left and right, and the next to fly left and right, and the fourth one bounces left and right. There are some Blocks in the floor, and if you're tall, you can Spin Jump through the first three Blocks and fall down to the Mushroom Platform below, where you can hit the last Block to make a Beanstalk come out. Climb up the Beanstalk to reach clouds in the sky with many coins and a Dragon Coin above them. Be sure to get the two coins beyond the edge of the clouds, and fall straight down from there. Skip ahead to Find a Message Block on this page.
If you don't have any way to reach the cloud platform mentioned above, then just go to the right from the Mushroom Platform with the green Koopa Paratroopas on it and jump on the Triple Swing Lift, then jump on the Pulley Lift going around a circular track, then jump on the Triple Swing Lift after that. Jump from there to the Mushroom Platform on the right.
Find a Message Block
There is a Message Block on the Mushroom Platform that tells you that you can hold L or R to slide the screen left or right.
After the Message Block, there is a red Koopa Troopa.
Next, there is a Pulley Lift on an octagonal track. Get on the lift and hit the ON/OFF Switch to change the track so the lift goes to the right. There is a green Koopa Paratroopa along the path of the lift, and then another ON/OFF Switch. Make the switch say ON, or the lift will go on the lower track and fall off the end.
Get the two coins above the lift, and beware of the Fuzzy on the circular track to the right of the coins. Yoshi can't eat Fuzzies. There are two more coins after the Fuzzy, and a Dragon Coin. Then there is a green Koopa Paratroopa, and below that, you find the Midway Gate.
After the Midway Gate, there is a Pulley Lift and a Fuzzy on the same track. The Fuzzy moves more quickly than the lift, so be careful. Jump from the lift to the Triple Swing Lift, and hit the Prize Block in the middle of the lift to get a Cape Feather.
Then you can either use the Lifts in the bottom of the screen if you don't mind skipping a 1-Up Chamber, or you can jump onto the Pulley Lift above and to the right of the Triple Swing Lift and let it take you to the right, where there are three green Koopa Paratroopas, three coins, and a Dragon Coin. At the end, go down the pipe to reach the 1-Up Chamber. Each row of three Prize Blocks can give you a 1-Up Mushroom if you hit the three blocks in the correct order. The correct order is secret, so you just have to hit them and hope that you get the correct order. After you have finished each row, jump up through the floor between the Prize Blocks to try the next row, and so on. Go through the pipe at the top.
If you used the lifts in the lower part of the screen instead of going to the 1-Up Chamber, you will reach two Triple Swing Lifts that have 11 coins and a Dragon Coin around them. If you went to the 1-Up Chamber, you can go left to get the coins around the Triple Swing Lifts.
After the Triple Swing Lifts, there is a Mushroom Platform and a pipe, then an octagonal track with a Fuzzy on it, and a Triple Swing Lift in front of that track. Ride on the Triple Swing Lift without letting the Fuzzy hit you, then get on the Pulley Lift to the right of the Triple Swing Lift, and hit the Bonus Block as you go past. If you have collected 30 or more coins in this level, it gives you a 1-Up Mushroom. If you have collected fewer than 30 coins in this level, it just gives you one coin.
After that, go through the Giant Gate to complete the level.
After the Level
The path to the east unlocks, and you can go to Donut Plains 4.
