Biography
Chambrea is a maid and worker at the Grand Lobby, she is seen briefly in the opening cutscene, at long distance insie the Grand Lobby, wearing a mask to cover her ghost traits. When Luigi was retrieving a briefcase of E. Gadd, he enters a room where he finds Chambrea cleaning with a duster. She spots the briefcase and takes a look at it interested. However, when noticing Luigi in the room, she immediately panics and swallows the whole briefcase, containing it inside of her belly and escapes the room through the wall.

Chambrea is fought by Luigi in various rooms in the RIP Suites. When found, Luigi tries to vacuum her but the briefcase in her belly prevents the Poltergust from doing so, causing her to laugh instead. Chambrea will attack using the briefcase when she charges at Luigi, causing him damage. She will also use her duster anytime Luigi tries to suck her to tickle him. When she escapes through the wall to another room, E. Gadd contacts Luigi and suggest him to use the Suction Shot at Chambrea. This helps Luigi by grabbing Chambrea and slamming her into the floor, decreasing her health. After defeating Chambrea, she will drop the briefcase out of her and will tickle Luigi one last time with her duster before finally getting vacuumed with the Poltergust.
