A few faint clicks echoed in the walls of the room, the plant retreating back into the chest it had been released. However, it got caught in its retreat, getting shut into the chest that had released gas.  The way it was trapped, both chests remained half opened, despite the room seeming to reset itself. A hiss sounded from the gas chest, it was refilling. However, open as it was, that was a problem for the group. They had very little time to get out of the room and move on.
