A few people said this end result was a little dark and unexpected, but it IS a character I dreamed up in high school, and the only thing more dramatic than the me of the present was teenage me. Basically, it's meant to be an acidic, black slime type life form that's hollowed out a marble statue to give itself a more solid form. As it moves, the marble cracks and gives it a greater range of motion. Something like that!
