Pipe Room

The Pipe Room is a room explored in Area Four of Luigi's Mansion.

With the Key from the Armory in hand, Luigi opened the Pipe Room. Immediately, some green Flying Fish started attacking the ghost hunter. To make matters worse, some Red and White Grabbing Ghosts appeared as well. Within the cramped room, Luigi managed to separate and capture every one of the ghosts inside his Poltergust 3000. The Pipe Room illuminated, but Luigi did not receive a Key. The plumber noticed a frozen barrel giving off an icy mist. As Luigi approached it, an Ice Elemental Ghost flew out. After Luigi captured it, he used the Ice Element to freeze the toxic waste river flowing through the room. Successfully having made a bridge to the other side, Luigi turned a red wheel on one of the pipes, stopping the waterfall on the other end of the room. Luigi walked to where the waterfall once was and claimed the Key to the Cold Storage, and continued on his quest to find Mario.

The Pipe Room is pretty filthy, containing an ancient crate, a bucket, and the aforementioned frozen barrel. The river of toxic waste is untouchable until Luigi freezes it.
