How to clear Green Switch Palace in Super Mario World for the Super Nintendo Entertainment System and Game Boy Advance.

How to Clear Green Switch Palace

To get a 1-Up, quickly jump over the red shell and jump on the P Switch, and wait for the unshelled Koopa Troopa to kick the red shell. Run to the right to see the shell hit all the red Koopa Troopas below. If the unshelled Koopa Troopa kicked the shell to the left, it will hit all the red Koopa Troopas, so you will get a 1-Up when the shell has hit the last one.

Go through the pipe on the right, then go to the right you will see a Green Switch. Jump on it and you will see an explanation of what it does. Press a button to complete the level. You will be asked whether or not to save the game. Now all the green Dotted Line Blocks throughout Dinosaur Land will now have Green Blocks in them. When you hit a Green Block, a Cape Feather will come out.

After the Level

Now that the green Dotted Line Blocks have been filled in, if you weren't able to reach the secret exit in Donut Plains 1, it is easier to reach now, because there is a Triangular Block at the base of a new wall of Green Blocks. Just run toward the wall of Green Blocks, and the Triangular Block will make you run up the wall, where you can easily reach the key and keyhole to unlock Donut Secret 1.
