Hidden Room

The Hidden Room (Japanese: 隠し部屋 Secret Room) is an optional room found in Area Two of Luigi's Mansion.

After a bit of a rough landing, Luigi finds himself in the Hidden Room. This room is full of treasure chests, and the plumber begins opening them. The plumber is caught off guard, however, when he discovers a Flash ghost inside one of the chests. Using the Fire Element function on his Poltergust 3000, Luigi is able to defeat the apparition. Luigi hopes that was the only ghost in the room. No such luck, however, as the ghost-hunter has to capture three more Flash ghosts before the room brightens. When it does, Luigi notices three chests still unopened. He raids them all, and inside one of them is a Blue Jewel, a Green Jewel and a Red Jewel. Luigi rejoices at his good fortune, and after celebrating, he uses the same mousehole to transport him back into the Butler's Room.

The Hidden Room is a small room with many treasure chests. Eight of them to be exact, including the one Luigi receives for brightening the room. The room's floor and walls are golden and as such the entire room sparkles with gold dust, like the Sealed Room. During the Blackout, one can come back here and capture a Speedy Spirit. Two vases are also located in the room (which are worth checking), as well as a mirror on the south wall that can be seen with the Game Boy Horror.

In the PAL Hidden Mansion, Luigi will find Shy Guy Ghosts instead of Flashes.

Ghosts in The Hidden Room during the blackout
