Pages 84, 85, 114, 115, 158, 159, 186, 202, 203, and 218.</ref> are small pocket levels that appear in ''[[Luigi's Mansion: Dark Moon]]''. They can be accessed only via [[paranormal portal|portals]] that often appear inside furniture or objects, and they teleport [[Luigi]] into the [[??? (Luigi's Mansion: Dark Moon)|ghost dimension]] when he interacts with them. They usually leave him on small floating islands or in small mazes.

To access a bonus challenge, Luigi has to locate a shaking door. Shaking doors can be found on fridges or coffins or as fake doors, and they are usually hidden from view or behind fake walls, requiring the player to hunt them down. Opening a shaking door pulls Luigi into a smaller level, where he must complete a set of tasks or minigames within a set time limit; these range from collecting several [[Red Coin]]s and normal [[coin]]s in a maze to finishing a snowman's face to capturing five [[Gold Greenie]]s before they escape to having a snowball fight with some [[Hider]]s. The minigame ends when time runs out or Luigi completes the given objective, the latter of which rewards him with a [[gem]] or a large amount of treasure, and he gets returned to the area he used to access the dimension.
