This part begins World 9. These are the stages shown in this part: World 9-1: This is a pretty tricky stage. It consists of many rotating blocks that you need to use to get through the stage. The main enemies here are Koopa Paratroopas. Star Coin #1: Using the Paratroopas or the red Koopa Troopa, bounce off one of them to reach and grab the first Star coin. Star Coin #2: Either jump off of a block at its highest peak, or bounce off of the green Paratroopa moving back and forth to reach the next Star Coin. Star Coin #3: Enter the pipe with the Piranha Plant that's between the yellow block and the red block. Using the red block in the next area, jump to the platform with the final Star Coin. World 9-2: This stage isn't too hard, but the final Star Coin can be kind of annoying. Star Coin #1: Stand on one of the blue platform, and wait for it to sink to the Star Coin. Star Coin #2: Stand on the blue platform, and wait for it to sink to the pipe, then run into it. In this room, you will see a Cheep-Chomp. Avoid it, and grab the Star Coin. If you're Fire Mario, kill it, and grab the three 1-Up Mushrooms that it releases. Star Coin #3: Using one of the Paratroopa's shells, destroy the Brick Blocks in the bottom area to reach the final Star Coin.
