ok, these guys are forest spirits in Soot & Ash’s universe, and for lack of a better name, i’m calling them Grori.
These big, flamboyant flowerpots start off as softball sized sprouts and take a few years to grow in the root systems of whatever fauna they find themselves near. The location and the plant life around them during their little hibernation influences their shape, coloration and markings pretty heavily, so theres a wild amount of variation in appearance. And although their size is pretty intimidating, most are very shy spirits and tend to keep out of sight unless their territory’s being threatened, so its rare to see one unless you’ve royally screwed up.

And Soot certainly doesn’t seem to get along with them so well.. maybe they don’t like the smell of old cinders on him, who knows.
