* AllMythsAreTrue: In-universe; The "Witchfield Worm" turns out to be a large ''Labyrinthodont'' that got marooned in the present.
* ArtisticLicensePaleontology: The ''Labyrinthodont's'' appearance is drastically different to how it would've looked in real life.
** The creature had rough scales like a crocodile instead of the smooth skin it would've had in real life.
** It was also far larger than any known species of ''Labyrinthodont''. It was large enough to be able to rear its upper body up like a snake and prey on cattle.
** Despite being an amphibian, the creature was able to spend way more time away from water than it should've.
* BuriedAlive: Ethan attempts to do this to Emily.
* DamselInDistress: Emily's role in this episode.
