Ok! So, I know Snakes don’t dislocate their jaws, but neither does the wendigo. It is however flexing his jaw to loosen it as it spends most of it’s time settled even though its a two part jaw similar to a snake. It can also flex muscles in it’s neck to widen it’s throat for swallowing large meals! 😀
Yeah, it’s a mythical creature so I’m making up stuff about them for my version. Besides, if their were a book on the anatomy of wendigo that proves me wrong I’d then be worried that wendigo are real and I would never leave my house. If wendigo are real then that means illithids could be real and I am NOT leaving the safety of my home when illithids are out there!
