* AdaptationDisplacement: The show was based upon a book series.
* DesignatedHero: Mona is almost never portrayed in the wrong despite being delusional and getting people into trouble because of her crazy beliefs that they're supernatural beings. Somehow, the adults are (most of the time) stupid enough to believe her. Her two friends, Charley and Lily, are no better either, especially since they often assist Mona and are equally as delusional as her.
* DesignatedVillain: Almost 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!"
