I finally drew my character's "dog"! Now he has a full image instead of existing as a few pixels in a piece of joke art 😆
His name is Thing! That's his name because his owner (Lumina) decided to call him that when she was a kid.
Thing started out as a stray and eventually became a family pet over time, although he still roams freely as he pleases.
