There is no cryptid creature.  That's just an urban legend started by paranoid locals and made famous by Stephen King, who jumped on the local rumors and ran with it. It's a local homeless French Jewish man, whom I let sleep in my car on rainy nights so that he can stay dry. Retarded locals think he is a demon or alien or whatever else they call him, because he is covered in scars and burns and Kabalic tattoos and number tattoos from being a concentration camp survivor from WW2.
