* AdaptationDisplacement: The show was based upon a book series.
* DesignatedHero: Mona. She is a delusional girl who gets people into trouble because of her crazy beliefs that they're supernatural beings, and somehow the adults are stupid enough to believe her and she's never portrayed as being in the wrong despite all that. Her two friends, Charley and Lily, are no better either, especially since they often assist Mona and are equally as delusional as her.
* DesignatedVillain: Pretty much all the so-called "antagonists" Mona believes to be supernatural monsters are really just normal people who haven't really done anything remotely villainous.
* EarWorm: "Show us your fangs! YAY, MONA!"
