I mean, we know there's creatures we don't know about. Aside from glimpses of creatures in Eichen House, and not knowing what Parrish is.... the Argents have a beastiary that is, according to Allison, over a thousand pages. Even if every monster we've seen is in there, I don't think we've filled it up yet. (Unless they wrote it in very big lettering, maybe? :P) But I don't think we're ever going to see all of the creatures that exist in the Teen Wolf universe. I wouldn't be surprised if we never find out what the beasties in Eichen House actually are.

As an aside, I still stand by what I've said elsewhere, saying something does not exist is entirely different from saying we don't know if it exists or not.
