World 3-3 - New Super Mario Bros
This is our Star Coin guide for World 3-3 in New Super Mario Brothers Wii. This is an underground level that has a lot of floating ice chunks for you to stand on. The water is not instant death. It's standard Mario water.
Star Coin #1 - The first Coin is hidden in an Ice T near the start of the level. To right right will be a Green pipe dropping Goombas. Just into the water and the Star Coin is under the T. Then use the ice flows to get back up top.
Star Coin #2 - Once past the Midway Flag you'll come to a Coin Star above an Ice Bro. Kill the Ice Bro and use the ?-blocks to make the jump to the Star Coin.
Star Coin #3 - After going up the next pipe you'll see a barrel in the bottom left. Grab this and take it all the way to the right. If you lose it, it will respawn. At the end of the level you'll see the final coin. Simply throw the barrel in the Star Coin to get it.
