Thought to be genetically modified , highley evolved organism. Although never actually sighted evidence points to its habits and breediung cycle. A voracious predator the sock monster preys on single socks always leaving behind one of the pair it has captured. Mystery surrounds this behaviour although zoologists surmise this may be an instinctual mechanism for long term survival. Able to cross great distances at speed and unseen there is almost no known method of defense.
Currently there is a research program to capture one and study its life cycle to provide some relief. The only known fact is sock monster numbers are proportional the number of people in residence at one location.
2 persons = 2 monsters, infreqent predation
3 persons = 3 monsters, increased predation, victims are rarely able to find socks
4 persons = 4 monsters, forget it , no known cure, no socks at all for anyone
