A Pillow Beaver not to be confused with Pillow Biter, is typically a mammal of the human variety. He/She will gather all of the pillows to their side of a sleeping area creating a dam like effect. This Dam prohibits the calm waters of natural sleep to wash over any other mammals in said sleeping area. They do this unintentionally for it is intrinsic in their nature, thus a Pillow Beaver.
