Monstrous Mondays: Scarecrow for Dark Places & Demogorgons

"Rain on the Scarecrow.  Blood on the plow.
Blood on the scarecrow. Blood on the plow" 
- John Mellencamp, Scarecrow

Is there anything more ubiquitous to the midwest than the cornfield?  How about that lone scarecrow in that field.  Standing silent vigil throughout the summer and into the fall.  Are you sure he is not watching you?

Scarecrow
Scarecrows are basic guardians similar to golems, but not nearly as powerful. Like typical scarecrows, their bodies are made of straw and cloth. The stumble about their assigned area poorly and attack most anything that wanders through it. Some Scarecrows are bound to a post. A Scarecrow can use their paralyzing gaze to imprison any trespassers (save vs. Courage, fail means victim remains rooted to the spot).
Scarecrows are assigned to protect a particular area. They never leave the area, even when chasing an intruder. They will attack anything, humanoid or animal-like in appearance that walks into its territory unless otherwise instructed by their creator.
A scarecrow is immune to mind-influencing effects, poison, disease, and similar effects. They are not subject to critical hits, subdual damage, ability damage, energy drain or death from massive damage.
Fire Vulnerability: Because of their straw bodies, Scarecrows are extremely vulnerable to attacks from fire. They take triple damage from all fire attacks.
