Slippery Rope Ladders

Slippery Rope Ladders, or Layer-Cake Desert-Secret, is the secret level in the second world of New Super Luigi U, Layer-Cake Desert. It can be accessed upon completion of The Walls Have Eyes. Clearing the level's main exit gives access to Soda Jungle.

Layout
Luigi starts the level in an icy area with Piranha Plants and eventually must climb up some rope ladders while avoiding enemies to reach the upper level. A pipe eventually leads to an area with a starry sky and the Goal Pole.
