A Job for a Plumber

B-1: A Job for a Plumber is the first mission of Haunted Towers in Luigi's Mansion: Dark Moon. This mission is about getting the Hydro Generator to work again.

Overview
Luigi gets transported to the Haunted Towers Entrance. He must shine the Strobulb into the rightmost flower to reveal a key to open the gate, granting him access to the Courtyard. Luigi must travel to the right area to access the Hyrdo Generator. Upon entering the Hydro Generator, Luigi sees a Slammer escape through the ceiling. Luigi should then go to the right part of the room, inspect a treasure chest to get a key, then exit the Hyrdo Generator and back into the Courtyard. After pulling a leaf from the door at the left area of the Courtyard, Luigi can access the Tower Lobby. There, Luigi should shine the Dark-Light Device toward a wall in front of him, causing a hidden door and Spirit Balls to appear. Promptly arriving in the Greenhouse, Luigi gets startled by spontaneous mischief caused by Greenies. When Luigi tries to leave for the other exit for the Tower Lobby, the Greenie closes the exit and battles him, this time using shovels as weapons. Luigi then should defeat the three Greenies carrying shovels if he wants to access the other side of the Tower Lobby. Luigi should then enter the Tower Lobby, climb up the stairs, and arrive in the Plant Nursery. There, he finds two carnivorous plants that snap at him. Luigi must defeat them by shooting a spiked plant ball at them. They guard a treasure chest; defeating them grants Luigi access to a key. After exiting the Planet Nursery and entering the Tower Lobby, Luigi must be careful not to step on the carpet trap that can make him fall into the area below him, forcing him to navigate back to the area he was in.

When Luigi arrives at the Skybridge, he sees a mass of crows swirling and flying through the bridge. Luigi must avoid getting hit by them; if he gets hit, he slides around from the impact. Passing the Skybridge gives Luigi access to the Laboratories. In the Laboratories, Luigi sucks in several Greenies followed by two Slammers. This brightens the room and grants Luigi access to balloon berries, enabling him to fly in the room. Luigi then should fly all the way up, leaving him in the Lounge. Luigi should use the door, which takes him to the Water Supply. After Luigi climbs up the stairs, he finds a bucket with yellow slime on it. A Greenie suddenly appears and takes the bucket. When Luigi defeats the Greenie, Luigi can use the slime to fill the bucket, thus putting ample weight in it. Luigi should then take the filled bucket to the switch closer machine, so it and Luigi can both activate the switch at the same time. Then, he can use the Strobulb on all lights at once. When Luigi is about to leave for the Bunker, a Gobber stops him. Defeating the Gobber completes this mission

Description
''The towers' machinery isn't active. I'm guessing the ghosts broke it already. We need to get the Hyrdo Generator running before we can search for the next Dark Moon piece.''
