Oop, Herald of the Stain

A once abandoned project that I resumed because it needed to be done.

Oop, an Eldritch creature. An entity that leaves a noticeable trail wherever it goes. Emissary of worse things to come? A bad omen? A trickster? Nobody knows what its intentions are, as it also has an inconsistent shape that changes when moving, which can drive any witness to madness.
