Parris is the closest thing to a villain in the greater Bonne-related mythos. They're a cunning, selfish sneak who's basically addicted to the mutagenic properties of Seabunny milk (and other fluids).

Like Bonne, they're not entirely human, only instead of being descended from nudibranchs, their people evolved from ticks (Parris Tick, get it?), and they're more susceptible to mutation because of it.

Lastly, they work for Carmilla (y'know, her: https://www.furaffinity.net/view/37490188/ ), using her many connections to feed their strange addiction. However, what started as a con to acquire regular fixes might've developed into something a bit more intimate...
