Foyer (Luigi's Mansion)

The Foyer is the entrance to Luigi's Mansion. When Luigi first explored the mansion and failed to open the Parlor door, a "gold spirit" dropped the Parlor key in the middle of the Foyer. When Luigi returned with his Poltergust 3000 later on, he found Toad bawling over the disappearance of Mario. Assuring Toad that he would find his brother, the lights permanently turned on, only to be darkened again by the blackout later in the adventure.

The Foyer is the only room (excluding Hallways) to have two floors. The first floor is blocked by a force field at first and requires a special pink key from defeating Chauncey. The second floor's north doors lead to the Parlor, while the west door leads to the Study, Master Bedroom, Nursery, and The Twins' Room, all home to a member(s) of the Portrait Ghost family.

The Foyer makes a small appearance in the Mansion Patrol mini-game of Super Paper Marios. In the mini-game the character must blast Boos in the foyer to earn points.
