art gremlin
A gremlin, but of the artist variety. They are generally mischievous, prefer the dark, and are highly food motivated. They spend long hours working on art, to the point of neglecting personal relationships, health, and hygiene. On the rare occasion that they appear in public, they may appear totally normal, or even cute.
