New Super Luigi U: Rock-Candy Mines-1 -- Mount Fuzzy

There are mine rafters at the start of the level and Fuzzies moving on paths. High up on the left side of the rafters is an invisible block with a Mini Mushroom. There's a mini pipe later on in the level that will lead you to some coins and 3 1-ups. The first Star Coin is in the center of a path with brick blocks and Fuzzies. Use a shell to get it. Go past the Green Ring and you'll see Fuzzies jumping in the air while moving on paths. Use the Ice Flower to freeze the Fuzzies and use the Fuzzies as platforms to stand on for a short while. The third Star Coin is in the center of another ring of Fuzzies. Freeze the Fuzzies so you can stand on them to reach the third Star Coin. The flag is nearby.
