New Super Luigi U: Sparkling Waters-1 -- Huckit Beach Resort

It's time to go to the beach! There are lots of Huckits, the crabs that throw rocks, here as many huts above the water. You can walk into the huts to find hidden areas with coins, Huckits, and item blocks. Use the water pillars to reach higher places. The first Star Coin is in the first hut. Enter the hut from the right side. Below the boardwalk is a pipe in the water. It leads to an 8-bit Luigi and the second Star Coin. Ahead you'll see Huckits in tiers of brick blocks over the water. Pound the ground from the top tier to reach the third Star Coin. Use the water pillars to reach the flag.
