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

How to Reach Star World 3

Star World 3 can be reached by finding the secret exit in Soda Lake, or by finding the secret exit in Star World 2.

How to Clear Star World 3

This is a very short level that has a secret exit and a normal exit. There is a Lakitu that flies overhead. If you hit the Gray P Switch, all enemies will turn into Gray Coins for a limited time, which means that the Lakitu will throw coins until the Gray P Switch effect wears off.

There is also a Yoshi Egg that will hatch if you approach it. If you feed the Mini-Yoshi five objects, such as enemies, coins, Grab Blocks, or if you feed it one power-up, it will grow into an adult Yellow Yoshi. If Yellow Yoshi has any color of shell in its mouth, it will make the ground shake whenever it lands, and will create dust clouds to the left and right. The dust clouds can defeat nearby enemies. This effect lasts until you spit out the shell or until Yoshi swallows the shell.

To reach the secret exit, hold X or Y to pick up a Grab Block (but be careful not to make a hole that you fall down through) and throw the Grab Block at the Lakitu to defeat it without destroying its cloud. Try to do this near the five Grab Blocks that form stairs so you can jump up those stairs to jump into Lakitu's Cloud after you defeat it. Once in the cloud, you can press the directional pad buttons to move in any direction. Go to the left of the leftmost stair in the Grab Block stairway, then go straight up to find an entrance to a small room. Go to the left and hit the Prize Block to get the Key, then go to the right and use it in the keyhole.

If you want to clear the level normally so you can keep the Yellow Yoshi, go through the Giant Gate on the right.

After the Level

If you went through the normal exit, you will go back to the Star Road entrance nearby. If you went through the secret exit, a path opens to the east, leading to another Star Road exit. This also gives you access to Star World 4.
