Song is Skrillex: Rock N Roll
These..... monkey, skeleton, things hang from the ceiling, waiting to strike. When somebody passes under them, they then live up to their name. They literally separate their top half, which, dangling only from their spine, they then use their legs to grab their target, then lift the bottom half back up. What happens next is unknown, because nobody has seen it happen, or rather, nobody that's ALIVE has seen it.
