New Super Luigi U: Superstar Road-5 -- Under Construction

This level has blocks that appear and disappear over purple water. Get an item from the item blocks if you need it, then jump to the second set of brick blocks. The first Star Coin is here, surrounded by brick blocks. Break them to get the Star Coin and keep going. You'll soon see some Red Coins. Farther ahead is a set of brick blocks that you must wall jump up. Next to it is the second Star Coin over the purple water. Wall jump to get it. Ahead are some Boos floating around. Nearby are coins that form a square. They surround an invisible block with a vine. This will take you to a giant 8-bit Luigi from Super Mario World, with the third Star Coin on top. Drop down on the right side to reach the flag. Bowser Jr. is in the background.
