New Super Mario Bros. Wii/World 1-6

Normal Strategy
Grab a Fire Flower, and spam fireballs to easily cross the level.

Star Coins

 * Star Coin #1: This one is hard to get unless you have a Propeller Mushroom, otherwise, you're in trouble. You need to jump off the Green Paratroopas to get to it.
 * Star Coin #2: Much easier...shortly after the first warp pipe you see a Star Coin on a floating platform. Just jump off of the rotating mound to get the coin.
 * Star Coin #3: Underneath the midway flag, there is a telltale. Jump through it to get to a hidden warp pipe. Once you have entered, avoid the Goombas and jump to the final coin.
