Peek-a-Boo Ghost House

Peek-a-Boo Ghost House, or Frosted Glacier-Ghost, is the ghost house course of Frosted Glacier in New Super Luigi U. It is unlocked by completing Ice Slide Expressway, and its own completion will unlock Wendy's Thwomp Castle.

Layout
The level starts in a ghost house with a platform that turns into coins when stood upon and some moving platforms and Boo Circles. Soon after, a Big Boo starts chasing the player across some moving platforms. Eventually, a door appears which leads to the Goal Pole.

Secret Exit
When the player collects Star Coin 2, they need to reach a nearby secret door which leads to the Goal Pole. The secret exit opens up Fliprus Floes.
