I just watched the first episode of Wellington Paranormal. It evinces the same humor as the original What We Do in the Shadows.

Watching it makes me think I should build a catalog of features indicating possession. This episode relies on three tropes:

• body-hopping: the demon switches rapidly from body to body
• demonic voice: even the dog speaks in a gutteral voice when possessed
• evil eyes: in this case, they glow blue

The episode also includes a hellmouth, which I need to document more often. A gate to the underworld is an ancient trope, but the term hellmouth is becoming more popular.

The demon, Bazu’aal of the Unholy Realm, is not a historical entity. I’m guessing it is a pastiche of Beelzebub and Baal.
