New Super Mario Bros. U: Frosted Glacier-2 -- Cooligan Fields

On the way to the level, we pick up Baby Blue Yoshi, which blows bubbles that turns enemies into coins or power-ups. The level is covered in ice, so moving around is difficult. Go under the blocks for the first Star Coin. Cooligans are all over the level and they're a little difficult to deal with, as they take two hits to defeat. Use the Ice Flower to freeze them. There's a Red Coin Ring past the midpoint. There's a 1-up in an invisible block on the platform next to the area with some pipes. There's an area between two pipes coming down from above. There's a Cooligan as well as coins in the area. Wall jump up between the pipes for the second Star Coin. There are ice pillars ahead. Go down the platforms and bounce off a Cooligan to reach a platform, then hop up the brick blocks to the third Star Coin. There are a lot of Cooligans on the way to the flagpole. This opens the path to the Fort.
