It is called The Lunar Eclipse, but It likes to be called Lunar instead, it is small and cute but very dangerous, do not trust it at all, do not aid it, it will kill you, it doesn't like the dark so it's room is very bright, Lunar is one of the smallest things in the facility, but also the third most dangerous one, Lunar has tried to escape it's room about 10 times but it is not possible, Lunar has gotten employees from the facility to trust it and it uses that trust and kills them afterwards,
