The Walls Have Eyes

The Walls Have Eyes, or Layer-Cake Desert-4, is the fourth level in the second world of New Super Luigi U, Layer-Cake Desert. It can be accessed upon completion of Wind-Up Tower. Clearing the level's main exit gives access to Spinning Sandstones. A secret exit leads to Slippery Rope Ladders.

Layout
Luigi starts the level in front of a Stone-Eye statue. Going to the right, there is a tunnel where an endless number of Stone-Eyes slide to the left. Exiting the tunnel, there will be three Stone-Eyes forming a bridge, and a Waddlewing roams above it. Next, there are pendulous statues, with a Warp Pipe and a Big Piranha Plant among them. After this section, Luigi encounters several shifting statues, followed by two more Big Piranha Plants. Three more Stone-Eyes help Luigi to get to the Goal Pole.

Star Coins

 * Star Coin 1: This coin follows a Stone-Eye in the first tunnel. Luigi must push it down using a Ground Pound to gain access to the Star Coin.
 * Star Coin 2: Luigi must Ground Pound the middle Stone-Eye in the area where the single Waddlewing is found. After this, he must jump, revealing a secret block with a Beanstalk. Climbing it, Luigi finds a bonus room with the Star Coin, some coins and a swinging statue.
 * Star Coin 3: Just beneath a statue before the Big Piranha Plants, above a pit.

Secret Exit
Luigi (who must be at least Super Luigi) must Ground Pound the piece of land between the Waddlewing section and a Mini Warp Pipe. He will break some Brick Blocks and reveal a hidden Pipe Cannon that blasts him to the secret Goal Pole. The secret exit leads to Slippery Rope Ladders.

Luigi Sighting
The player can find Super Luigi's crouching 8-bit sprite in the underground bonus room that is reached entering a mini-sized Warp Pipe. However, there are no Mini Mushrooms in the level, and one must be obtained from another level.

Enemies

 * Waddlewings
 * Big Piranha Plants

Trivia

 * The name of this level is a pun on The Hills Have Eyes, which is the name for various works, or from the Japanese proverb: "Walls have ears, and the shōji (Japanese windows made of paper) have eyes."
