New Super Mario Bros. Wii 9-2 -- Swimming With the Fishes

This level is a water level, despite World 2 being a desert. It's another level where you have to dodge the big spiked fish, who cannot be frozen. This level has platforms that go down when you step on them, but return to their normal position when you step off. I used the 3rd one to get the 1st Star Coin. I rode the 4th platform eown to the green pipe to go through it. The 2nd Star Coin is there, as well as another big fish that will try to gobble you up. If you have a Fire Flower, you can use the fireballs to kill the fish for 3 1-up Mushrooms. Things get a little tricky after you leave that area. There are sets of blocks that expand and contract, and move as they do so. They will put you in danger and take you out of it. Making matters worse are the Piranha Plants in the pipes. Near the end is the 3rd Star Coin. I sent shells into the blocks to clear a path and ran under the ledge to get the Star Coin. After that, I made it to the goal. This took me 14 tries.
