New Super Luigi U: Soda Jungle- Fort -- Stone-Snake Tower

There is purple water in this fort, and it rises, so you'll have to keep moving. Go past the Grrrols and you'll see a snake block. It will snake throughout the fort. Wall jump to reach the first Star Coin. Grab the Red Coins if you like. On the left wall is a P-Switch which turns coins into blocks, leading you to the second Star Coin between two spiked ball and chains. Silver Coins also appear. Near the top, a second snake block will appear and the snake blocks will take you to the boss door. Near the left wall, the passage will narrow and you'll have to jump from snake block to snake block, following the coin arches. Jump at the first coin arch to reach the third Star Coin, 8-bit Luigi, and a 1-up. Go through the boss door and Kamek will make Boom Boom a giant. Stomp three times to win.
