Old Clockworks

Old Clockworks is the third of the mansions Luigi visits in Luigi's Mansion: Dark Moon. E. Gadd tells him that a Dark Moon piece is in the highest point of the clocktower. E. Gadd tells Luigi it closed shortly after opening due to some horrific accidents. As its name indicates, this 'mansion' is fairly clockwork themed, featuring various mechanical rooms. It is also somewhat of a desert theme, as its location features a lot of sand, as does the mansion itself. This is where Luigi can find Yellow Toad. It is also shown here several Boos save the yellow toad from a long fall, before sticking him in a painting.

History
The Old Clockworks originally produced, according to E. Gadd, the finest timepieces long ago. The factory itself is the oldest of the mansions as it is the Evershade Valley's ghosts favorite haunt. The factory was built on top of some ruins. The owners of the clockworks seemed interested in this as mining and excavation equipment can be found strewn about the ruins. There is also a stairway leading from the factory into the ruins. It is unknown why it closed down, but several jackets, coats and hats can be found still on racks, and the large amount of equipment and crates left behind, suggests something happened within the factory itself to cause it to be abandoned.
