East Corridor

The East Corridor is a room in Treacherous Mansion in Luigi's Mansion: Dark Moon. Located on the second floor on the east side of the mansion, it contains entrances to the Nautical Exhibit, Study and Inner Courtyard, as well as a Trapdoor where the door to the Train Exhibit would be.

The room itself has fairly few notable features. There are a few Gargoyles littered around that can be blasted with the Strobulb for coins, some money on the rafters and a window that looks out onto the Terrace, with not much else to be found.

History
In E-3: A Train to Catch, Luigi explores the East Corridor to reach the Study and Nautical Exhibit. There are also a few Greenies that attack here when Luigi tries to use the Trapdoor to enter the Train Exhibit, the room never gets lit otherwise.

In E-5: Paranormal Chaos, the East Corridor is mostly empty and used merely as a route to the Nautical Exhibit. However, if Luigi tries to look through the window to the north, an earthquake occurs and he jumps back instead.

In E-Bonus: Terrifying Invasion, the East Corridor is one of the rooms that may be infested with ghosts. Oddly enough, two of the ghosts Luigi will always fight here if it's infested are two Mummies, despite the fact they never normally show up in this sort of area in the main game.
