New Super Mario Bros. U: Meringue Clouds-1 -- Land of Flying Blocks

This is a unique level. Parts of the level move around, but the ground does not move with it. You can get the Acorn Mushroom here. Dodge the flying squirrels and go through the red pipe in a cluster of pipes with Piranha Plants. It will take you to an area where you must run across brick blocks that appear out of midair for the first Star Coin. Return to the main level and find a set of three blocks that go as follows: brick block, item block, brick block. Stand on top of them to make brick blocks appear to the second Star Coin. Next are some mushroom platforms with a pipe that takes you to the midpoint. This part has moving clouds for platforms, which Mario can easily stand on. Past the Red Coin Ring is the third Star Coin surrounded by brick blocks. Pound the brick blocks to break them and get out of the area. There are giant Piranha Plants all over the rest of the level. A series of brick blocks will take you to the flagpole. This opens the path to Meringue Clouds-2 and -3, as well as a Mushroom House.
