The Moose Man is an urban legend formed by a little city in the USA.
They say that if you go through a certain sewage tunnel, you will end up in the woods, except these woods don't exist in the real world. Go far enough and you will risk getting seen by the Moose Man, where only god knows what he will do to you.
Except that's not how he works.
The moose man is only a fruit of labor, a decoy.
The real threat is the omniscient, shadow-endowed entity with a moose skull for it's head.
If it visits you in the middle of the night, you will be paralyzed as if you are in a sleep paralysis dream, it will stand and stare at you from across the room.
Soon enough your insides will begin to throb with mutations and out of your head will erupt a moose skull, as well as skin tumors and claws on your hands. (the entity fucked up while making the blueprint so you get claws instead of hooves)
The antlers will grow so large they will be pressing against your brain, leading to brain damage. You will only be able to be rabid. You will run into the woods and any noise you hear will startle you, leaving you with a fight response.
This is the Moose Man that people know, the fake lure. Maybe tonight you will be the next victim...
