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.

History
The Old Clockworks originally produced, according to E. Gadd, the finest timepieces long ago. It closed sometime after opening due to a large amount of unexplained horrific accidents. It is unknown what these accidents are exactly, but several work coats can be found jammed in the large gears found inside the Old Clockworks.
