This is Glu, he is a creature I've been drawing for a while, has made appearances in my notebooks since I was in elementary school. He isn't really a dragon, it's hard to explain, I guess the best way to describe them, would be like a Doberman mixed with a dragon.
Despite what it might look like, he has fur and not scales, it can be either velvety and short, or long and hair like. He can't speak but makes noises, however he communicates with thoughts. The bone part is a mask that's fused into his skull. While his tail isn't docked, his ears are cropped (his choice, because the bone mask made his floppy ears feel uncomfortable).
He drools ink, which is kind of where his name comes from... Yeah I don't know what I was thinking, I guess just ink is gooey, glue is also gooey, ink is sticky, glue is sticky.
Nobody knows if he actually sees with his eyes, he only stares blankly past people, but he can definitely perceive you like he has vision. His eyes are kind of hollow, and what looks like space can be seen inside, sometimes it's just a void.
Feeds on nightmares, and is forced to inflict them on people, but normally tries to bring joy to the person after he's fed (good dreams, gifts, comfort, favors, ect). His intent is not to be evil, he can't change how he was made.
Normally doesn't have wings, but can 'grow' them at will, they help him fly, but not too high, it's more akin to hovering. If you try to touch his wings, you'll realize that they're not actually there; some people may see the wings as what they truly are, smoke.
