New Super Mario Bros. U: Frosted Glacier -1 -- Spinning-Star Sky

After finishing Sparkling Waters, we're going to Frosted Glacier, before we head to the Soda Jungle. This is a challenging level. The stars are large and can freely rotate, but won't move until you stand on them. Below them a patch of Nippers or the void, so platforming must be precise. If you're not ready to jump to the next platform, just jump in place so you won't fall. The Acorn Mushroom is very useful here. The first Star Coin is out in the open. Go to the right of the Star Coin, and jump from the blocks to get it. There's a brick block at ground level. Hit it to make a vine appear. It will take you to a higher part of the level, with more stars and the second Star Coin. The stars will be lower and lower until you reach the midpoint. Past the midpoint is a Green Ring. There are note blocks between the stars, which makes platforming a little easier. Glide over the Nippers to an invisible area with a Starman. Use it to run over the Nippers to an invisible area with the third Star Coin. The flagpole is nearby. This opens the path to Frosted Glacier-2.
