Rooftop Pool
The Rooftop Pool is a room inside of the Haunted Towers in Luigi's Mansion: Dark Moon. The Rooftop Pool can only be accessed by inspecting the reclining chair inside of the West Bathroom. This large room, as the name implies, has a pool in the middle with a diving board. There are frog statues on three of the corners of the pool; the other corner has stairs to get in and out of the pool. There are many vines creeping along the windows and floor of this room as well as several hanging plants.
In B-4: Pool Party, Luigi needs to make his way to the Rooftop Pool in order to find the Crypt Key that was stolen by the Boos from the Crypt. When Luigi gets to the pool, he should shine his Dark-Light Device on the top left corner of the pool. This will reveal a frog statue, and after all the Spirit Balls are vacuumed, it will spit out the Crypt Key. When Luigi approaches, a Sneaker will steal it. Luigi needs to fight four Sneakers after this encounter. After he defeats them, the Polterpup will steal the key from Luigi and jump out the window, ending the mission.
