How to clear Yoshi's Island 2 in Super Mario World for the Super Nintendo Entertainment System and Game Boy Advance.

How to Clear Yoshi's Island 2
If you're Fire Mario, walk to the left and then hold X or Y to throw a fireball so that you won't throw a fireball to the right. There is a useful item up ahead that you don't want to hit with a fireball. Go to the right and there is a red Koopa Shell, followed by eight Red Koopa Troopas. If you're not yet holding X or Y, walk to the left before you start holding X or Y so you don't hit the shell with a fireball, then touch the shell to pick it up, then jump onto the ledge with the Koopa Troopas and let go of X or Y to kick the shell at the Koopa Troopas and get rid of them. If you hit all eight, you get a 1-Up.
After that, there are two Prize Blocks, and if you visited the Yellow Switch Palace, there will be a Yellow Block between them. The Prize Blocks each contain a coin, and the Yellow Block contains a Super Mushroom.
After that, there are two Prize Blocks. The first one contains a coin, and the second one contains a Yoshi Egg. After a moment, Yoshi hatches out of the egg. Jump on Yoshi's back and you will ride around on Yoshi. You can press X or Y to make Yoshi stick out his tongue, press B button to jump, and press A to hop off of Yoshi's back. If you go too far away from Yoshi without hopping onto his saddle, Yoshi will disappear. If you get hit by an enemy, Yoshi will run away, but you can try to hop back on before Yoshi goes off screen.
While on Yoshi, go to the right, then hit the Message Block to see a message about the Spin Jump.
Yoshi can eat the Red Berries if you jump so his mouth is near the berry. He can also eat berries if you press X or Y and hit the berry with Yoshi's tongue. If Yoshi eats ten red berries, Yoshi will lay an egg that contains a Super Mushroom.
After that, there are four coins and a Dragon Coin, as well as a red Unshelled Koopa Troopa that jumps into a red shell. If you have Yoshi stick out his tongue and eat the Koopa in the red shell, Yoshi will spit three fireballs the next time you press X or Y.
After you get the coins where the Koopa Troopa was, there are two more Red Berries, followed by a green Unshelled Koopa Troopa that jumps into a green shell. If you have Yoshi stick out his tongue and eat the Koopa in the green shell, Yoshi will spit the shell out as a projectile the next time you press X or Y. So be careful not to let the shell hit you when it bounces off the wall!
Get the Dragon Coin that was above the green Koopa Troopa.
To the right, there are two more Red Berries, and a Chargin' Chuck. Yoshi can't eat Chargin' Chuck, so just stomp on it, and bounce off to reach the three coins and Dragon Coin.
To the right, there is a Message Block that explains about the Midway Gate, followed by the Midway Gate. Go through the tape in the gate.
Next, there are two pipes, followed by three Prize Blocks. The first and last boxes each contain a coin, and the middle one contains a Yoshi Egg. If you're still on Yoshi, the egg will hatch into a 1-Up Mushroom. There is another Red Berry after the Prize Blocks.
Next, there are some ledges, and two Monty Moles pop out of the wall, and if they come all the way out, they chase you. Yoshi can eat them or stomp them. He can even eat them when they are still digging through the wall.
The third ledge has two Blocks above it. You can hit the rightmost block to make a Beanstalk grow out of it. However, to climb the beanstalk, you have to press A to hop off of Yoshi if you're still on, since Yoshi can't climb the vine. If you do climb the vine, there is a platform of Cloud Blocks, with four normal coins and a Dragon Coin above them. If you climb back down the vine, Yoshi might still be there.
If you go to the right from the base of the Beanstalk, there is a Red Berry, then another hill that a Monty Mole comes out of. Get the three coins and a Dragon Coin on top of the hill.
After that, if you visited the Yellow Switch Palace, there is a Yellow Block, which contains a Super Mushroom.
After that, there is a Red Berry, then a Monty Mole that pops up out of the ground, followed by a Pink Berry. The Pink Berry doesn't have a special effect unless Yoshi eats two of them, but there is only one in this level.
After the Pink Berry, go down the pipe. There are six Flying Prize Blocks. You can pick up the Grab Blocks and throw them upward (hold X or Y to pick one up, then hold the Up button and let go of X or Y to throw it upward) to hit the Prize Blocks. You can catch and throw the Grab Blocks multiple times, but they eventually disappear after you pick them up.
When you're done in the hidden room, go through the pipe on the right.
There is a Jumping Piranha Plant in the pipe on the right. After that, there are Blocks around a P Switch, and a Chargin' Chuck to the right. Jump and hit the Block under the P Switch and stomp on it, then jump on the Brown Blocks that the coins turn into. Then go to the right and jump and hit the moving tape on the Giant Goal to complete the level.
After the Level
The path to the north will be unlocked, so you can go to Yoshi's Island 3.
