This story has a link to a motion picture that may surprise you.
That's right. The film was Night of the Demon. It is truly a spooky film with even spookier production troubles.
The fantastical demon, the title character, is a critter cum Baphometian type devil. They did a great job photographing him. He, of course, WAS REAL.
He later had a championship bout with Hulk Hogan whom he "toasted" with his fire-breathing skills.
Some popcorn for you:
Another Baphometian Critter Demon is featured in The Devil Rides Out.

That thing was real. Did you see that?
