So I've been browsing cryptidz-wiki and found that in Maryland (the State the show takes places in), has legend of a Goat-Man. And in the Episode "Your it" Kelsey mentions decapitating a goat-man as her destiny. Maybe the Show could work that into itself.
I'll leave the link to the Goat-Man http://cryptidz.wikia.com/wiki/Maryland_Goatman
