Switch Palace

In Super Mario World, there are many colored outline squares in the levels. The squares can become ! Blocks by activating the Switch Palace, which is usually found by accessing the secret exit of a level (the only exception being the Yellow Switch Palace.) The ! Blocks are used mainly as platforms for Warp Pipes, Secret Exits, and ? Blocks, but also contain helpful power-ups. The best thing about ! Blocks is that they always contain the same power up! (Example: Yellow contains Mushrooms)
