Parlor (Luigi's Mansion: Dark Moon)
From the Super Mario Wiki
The Parlor (known as Parlour in PAL version) is a room in the Gloomy Manor in Luigi's Mansion: Dark Moon. This area is accessed by taking the bottom door in the Master Hall. The most notable feature of the Parlor is the phonograph in the center of the room and the grandfather clock that displays the time that the Nintendo 3DS has set. Several paintings adorn the wall, one of which can be removed to reveal several coins, bills, and Gold Bars. The ceiling fan can be vacuumed to lower the ceiling and reveal a stash of coins, bills, and gold bars. There is a fireplace that acts as a secret passage to the Lab.
During Gear Up, Luigi needs to go to the Parlor in order to find one of the Slammers that stole a gear from the mechanism in the Foyer. The ceiling fan will only release money during this mission as well. In Visual Tricks, Luigi has to utilize the secret entrance to the Lab via the fireplace in the Parlor. In Sticky Situation, the Parlor may be one of the rooms covered in spider webs.
