Haunted Towers

Haunted Towers is the second mansion Luigi travels to in Luigi's Mansion: Dark Moon to find a Dark Moon piece. This mansion, besides being partially destroyed by a giant oak tree growing in the middle, has a greenhouse-like theme, which can be compared to the forest worlds of the mainstream Mario games. The mansion contains six floors and a basement, making it the tallest in the game. Luigi meets a Toad assistant here. The mini-bosses are The Three Sisters, fought in the Old Graveyard, and the main boss is the Harsh Possessor, which possesses a staircase in the Tree House at the top of the mansion.

History
Haunted Towers was abandoned for some time and was used as a greenhouse prior to its abandonment, but the whole area became infested with plants and started to fall apart. Everything in the mansion runs off a Hydro Generator. The Haunted Towers were owned by The Three Sisters, as three portraits of women can be found in the Family Room, toys for a child in the Rumpus Room, and a Bedroom in the west tower. For unknown reasons, there is a large graveyard behind and under the mansion.

Trivia

 * This is the only Mansion to have its own personal opening cutscene for each mission.
 * 6F (5F in PAL regions) is seen as ? instead of 5F
 * Located in the Rumpus Room (Play Room in PAL Version) there is a pink doll house. The house appears to be the Haunted Towers, except without the huge tree in between the east and west tower. It is presumably what the building had originally looked like before it was abandoned (implied by the window matching the window of the Rumpus Room it gives the player a view through), indicating that after this happened and became overgrown with plants, the giant tree destroyed the middle tower.
 * If the player positions Luigi under the leaky pipe in the staircase, Luigi will take off his cap and uses it to scrub his in between his arms while whistling a tune, as if he is in a shower.
