Piranhas in the Dark

Piranhas in the Dark, or Layer Cake Desert-3, is the third course of Layer-Cake Desert in New Super Luigi U. It is unlocked by completing Spike's Tumbling Desert, and its own completion will unlock Wind-Up Tower.

Layout
The level starts in a desert setting with a Warp Pipe that will take the player(s) to the underground portion of the level. There is a secret Super Star above the warp pipe. The next portion of the level is very dim, with spotlights lighting the way throughout the course. It mainly consists of tilting platforms that move up and down.

Star Coins

 * Star Coin 1: Above the first Piranha Plant.
 * Star Coin 2: Underneath the Piranha Plant on the last platform before the second flat area.
 * Star Coin 3: In a green pipe near the end of the level with a Big Venus Fire Trap on it that must be killed with a Fire Flower or the secret Super Star.

Luigi Sighting
If the Piranha Plant guarding the Star Coin is killed, they will see an 8-bit Luigi.

Enemies

 * Big Piranha Plants
 * Fire Bros.
 * Big Venus Fire Traps

Trivia

 * The Big Piranha Plants of this level are seen on top of pipes, but don't go in them as if they were on the ground. This also occurs near the beginning of Slippery Rope Ladders. This may be because the pipes themselves are normal-sized rather than huge.
