Donut Plains 4

Head right and prevent the Koopa from getting into the yellow shell; if it does, it becomes invincible.

If the Koopa gets in the shell, quickly climb onto the pipe to avoid it.

Run and jump to the higher ledge to get the first Dragon Coin.

Drop off heading right, over the yellow pipe, and onto the extending green pipe.

Jump onto the next pipe, timing your jump to avoid the Piranha Plant that emerges from it.

Enter the pipe.

In the underground area, make your way across more extending pipes to the far end, avoiding Flying Koopas.

Enter the pipe at the end to return to the main level.

Go right and hit the bottom of the floating platform to knock off the hammer-throwing enemy.

Use the platform or run up the side to get to the next ledge.

To get a 1-Up, jump on the first Koopa and throw its shell right to make it bounce around and hit enemies.

Go down the slopes and hit the blocks to get coins and a power-up.

Hit the right set of blocks to make them rotate, allowing you to pass through.

Enter the next pipe to reach an underground area.

Avoid the Koopas and, at the gap, jump on them to make it across.

Collect the third Dragon Coin.

Exit the underground area to be thrown out near the checkpoint (an auto-save point you restart from on death).

Head right, over the gap, and hit the block to get Yoshi.

In the next hole, you will find the level's fourth Dragon Coin.

Go right until you reach a new block; hit it at the right time to get the power-up you want.

Hit the enemy on the platform from underneath again.

Use the platform to continue heading right over jagged landscape, avoiding or killing Gombas parachuting in or on the ground.

At the next gap, hit the platform-bound enemy from beneath and use the platform to get across the gap.

Enter the exit.
