Chambrea

Chambrea is the second boss encountered in Luigi's Mansion 3. She is first encountered on the first floor of the Grand Lobby and is subsequently fought in various hotel rooms in RIP Suites after Luigi locates the room to retrieve a briefcase. Defeating Chambrea rewards Luigi with the elevator button to the third floor and allows E. Gadd to supply Luigi with Gooigi.

Appearance
Chambrea is first seen traversing the elevator area in the Grand Lobby, dusting various furniture and surfaces in the room.

When next seen during Luigi's time on the fifth floor, she is found in Room 507 and is still following her duty to clean and dust. She is distracted when she spots E. Gadd's briefcase and examines it with intrigue. Luigi, watching through the door, panicked and steps inside with no heed to the door slamming shot. Chambrea turns around and is startled by Luigi's presence, tightly withholding the briefcase and considering her options. She then swallows the briefcase and attempts to float through the wall into the next room, though is briefly unable to pass through due to the solid briefcase in her now enlarged stomach.

Luigi pursues and combats her in various rooms before eventually pulling the briefcase through the surface of her stomach and finally capturing her.

Battle
Chambrea will be hiding in a room she has entered, but can be quickly spotted and drawn from her hiding place. She has few offensive actions, as she will often shoulder charge at Luigi when she is not stunned or being sucked.

However, her most difficult feature is her immunity to suction, as she cannot lose health from suction. She will instead simply become stuck in the maw of the Poltergust G-00 due to the solid briefcase inside her belly, where she will laugh and tickle Luigi with her duster until he releases her.

She is vulnerable to the plunger, which can be fired at her stomach and then gripped, from where Luigi can slam her repeatedly around the room to reduce her health.
