Master Suite

The Master Suite is an area in Luigi's Mansion 3. It is located on the fifteenth and highest floor of The Last Resort. The Master Suite can be accessed after recovering the fifteenth floor elevator button by defeating DJ Phantasmagloria in The Dance Hall.

As soon as Luigi enters the living area of the Master Suite, a video of Hellen Gravely appears on the projection screen. She congratulates Luigi for making it thus far, but warns him that it is not over yet. She then reveals that she plans to capture Luigi herself and give him to King Boo as a present. She also reveals Mario's painting is hanging above her desk. After the video, Professor E. Gadd calls Luigi and tells him to face off against the hotel owner and rescue his brother.

To the right of the living area is a withered tree surrounded by sand. In the northwest corner of the living area there is a drain leading to the purple gem. In the northeast corner there is another drain. Gooigi must pull off the cover with a Suction Shot, then enter to get to a hidden area with several Gold Spiders and a large fan. There is another pipe in the southeast corner of that room which takes Gooigi up to a chain, which he must pull to raise the projection screen, revealing a hidden door leading to the main hallway.

There are four keys hidden in the Master Suite, which have tops shaped like King Boo's Crown. There is a blue key, a green key, a yellow key, and a pink key.

The blue key is found in the bathtub of the master bathroom. Luigi must turn the faucet until the key pops out.

The green key is found in the smaller library in a puzzle. Luigi must turn the pinwheel in the southwest corner until the couch flips over, revealing the key as well as a miniature model of the Gloomy Manor, which he can look into to reveal a Gold Goob.

The yellow key is found in the master library. When Luigi goes to get the key, a laser defense mechanism starts, preventing him from getting it. He must avoid the lasers and walk down to the fuse box, then pull it off with a Suction Shot to disable the lasers, allowing him to get the key.

The pink key is hidden in the master bedroom. Luigi must use the Suction Shot on a mannequin, revealing a pendulum platform and the key behind a painting. Gooigi must ride the pendulum up to the key. The yellow gem can also be found higher up.

There is a large sculpture of King Boo in the far north end of the Master Suite. After collecting all four keys, Luigi must place them in the statue's tongue to open a vault, revealing Hellen Gravely's location. She berates Luigi for messing up her hotel and capturing her staff, as well as capturing her ghost cat, Polterkitty. She reveals her true form and shuts the vault, challenging Luigi to a battle. Hellen Gravely's battle consists of Luigi and Gooigi working together to reroute lasers to reach her. Just before she is sucked up, she puts on powder to revert to her original form, then disappears.

Luigi is then able to use the Dark-Light Device on Mario's painting, resucing him. He and Luigi hug and rejoice. Just before Luigi leaves, Mario shows him a door hidden behind the television. This door leads them up to the Rooftop, where Luigi is able to rescue Princess Peach and battle King Boo.

Due to Hellen Gravely's fondness of King Boo, several of the objects and furniture in the Master Suite resemble King Boo, including trash cans, pillows, and slippers. There are also paintings and sculptures of him found in the main hallway. Even the gems in the Master Suite are shaped like King Boo.
