The Scuttle — A friendly creature for the deepslate layer
Like the magmapod, the scuttle is a mob I came up with when I was playing around with Mojang's mob vote art style. Here's a short description.
The scuttle is a small, skeletal, surprisingly adorable serpent that can be found in the deepslate layer. When you find bones sticking out of the ground, don't be fooled; they're actually the tails of scuttles burrowing for coal! When they emerge, some coal will also surface, allowing you to replenish your torch supply below Y=0. When a scuttle dies, it drops its tail, which can be made into fast-traveling bone arrows or placed to decorate your haunted graveyard.
