Luigi's Mansion: Dark Moon -- Gloomy Manor - Confront the Source

Gadd found out that the paranormal signal is coming from the Cellar. He believes in Luigi and wants to stop whatever's causing the mess. We have to take the elevator to reach the Cellar. He then hands us an enormous key to use the elevator, but warns us it may be unsafe. He'll keep an eye on us from the Bunker.

Lobby
We land in the Lobby, in front of the elevator. We can't go anywhere else. Luigi unlocks the elevator and steps inside. It's initially pleasant, until the power in the elevator fails and it plummets like it's in the Tower of Terror. It crashes into the Cellar.

Cellar
Shine the Dark Light on the coin picture for lots of money. You'll slide down the stairs. Under the stairs is a treasure chest with more money. The place is covered in webs. Approach the big web in the back and pull the stringy web. This will make a giant spider appear. It will try to attack Luigi, then fall asleep. It will attack if you get too close. When its eyes are open, use the Strobulb to stun it, then grab the web again. Drag it to the suit of armor with a torch. This will light the web on fire and a ghost with a Dark Moon piece will appear. It will attack you. When it runs into a wall, stun it and vacuum it. This will remove a layer and the ghost will fly back to the spider. It will crawl up the front wall and break through the back wall and sit on a web there. Spin the ceiling fan to catch the dangling web on fire and let it hit the other webs. Stun the giant spider and drag the web to the suit of armor that tries to stab you. It will pick up the web and hold it for you. Spin the fan again. The spider will fall and the ghost appears. Remove another layer and it will return to the spider. It will destroy the fan and the stabbing suit of armor. Near the spider is another suit of armor with an unlit torch and a web ball. Set the web ball on fire with the suit of armor near where the ceiling fan was and return. The place will start falling apart and columns will block your path. Be careful. Burn the web around the suit of armor and light its torch. Stun the spider, grab the web, and set the web on fire. This releases the ghost and he'll disappear once you vacuum him up. This releases a piece of the Dark Moon. Grab it. The spider will come back to life, shrink, and leads the spiders out of the Cellar. The place starts shaking as all the spiders leave.

Gadd thinks it's amazing that ghosts can possess other beings. He notices the Dark Moon and brings us back, but not before a victory dance interrupted by a spider.

Gadd says that the ghosts have likely spread the remaining Dark Moon pieces all over Evershade Valley. The piece we recovered is covered in corrupted energy. Gadd cleans it up. The fog clears to reveal a new mansion. We can now go to Haunted Towers. But first, there's an extra mission in Gloomy Manor once we find the remaining Boos.
