New Super Mario Bros. U: Frosted Glacier- Fort -- Freezing Rain Tower

oThis level has lots of icicles dangling from the ceiling. If they shake, it means they're about to fall, which will hurt if they land on you. They also act as spikes on the ceiling. The large icicles serve as platforms. Use the two large icicles as a platform to a tilting platform that leads to a Red Coin Ring. Another large icicle will lead you to a another tilting platform with the first Star Coin. Go up to the midpoint. Just above it is a yellow platform that fills the whole room. Take the platform up to the boss door. On the way, you'll see Dry Bones and the second Star Coin, which is on the right. Past the second Star Coin is a narrow gap on the left. Jump to it to reach an invisible area with the third Star Coin. Use the POW Block to get rid of the Dry Bones. At the boss door, two large icicles will drop down near the walls. The one on the right will help you reach an invisible block with a power-up. Kamek will power up Boom Boom so that he jumps around. Stomp him as usual. This opens the path to Frosted Glacier-3.
