Super Mario Bros. 3 Cheats

World 3, Level 8 Cheat
When you get to the first section with two orange blocks and a turtle between them, jump on the turtle twice to send it spinning and break the blocks. When it breaks the one on the left, a vine will appear. Clib up the vine and you will see a music note block. Wait to jump on it until the section that had the turtle has risen up out of the water, because when you jump on it, something will pop out that might run away. You can get a mushroom or a fire flower.
