You accidentally entered an elevator that goes up an infinite number of rooms/levels. You've been stuck there for a few hours before deciding to stop at level 580. Your met with a room that seems to go on forever. The room is also filled with toxic gas, most of the furniture are completely destroyed. You also hear someone's manic laughter followed by loud breaking sound, you see a man with a piece of raw meat for a head destroying the furniture around him with an axe.

"WHERE ARE YOU!!??"

He yells as he continues to search for the stray mouse.
