World 6-2 (New Super Mario Bros. Wii)

This is an underground level, with many rotating circular platforms, much like the ones in World 1. The main enemies in this level are Spinies and Swoopers. There are also some Big Piranha Plants and at the end of the cave, there are two Sledge Bros. right before the Warp Pipe to exit the cave.

Star Coins

 * Star Coin 1: Shortly before the checkpoint, Mario and co. must use a Spiny to break the Brick Block that is covering a hidden area, thus opening the path to the first Star Coin.
 * Star Coin 2 (pictured): There will be three Piranha Plants; one inside a Green Pipe and the other two surrounding it. Mario and co. must have an Ice Flower and freeze the Piranha Plant in the Pipe while it is at its highest point, then use it to jump up and get the second Star Coin.
 * Star Coin 3: The right of two spinning rock wheels contains a Pipe which, when entered, will lead Mario and co. to an area with a P-Switch and four Spinies. Hitting the P-Switch will turn the Brick Blocks into Coins, thus making the third Star Coin accessible.
