Assissin
A small, dwarf like creature that lives either under your bed, in your closet, or possibly both. BE WARNED: These creatures are insanely strong and witty. If you ever have the displeasure of meeting one, simply run away as fast as you can, or if you're in your bed, hide under the covers until the screaming stops.
Dude, did you see that Assissin in your sisters room?

No. What were you doing in my sisters room?
