This is a creature known as a "Flying Polyp", created for my illustrated Lovecraft bestiary. [The flying polyps were a] horrible elder race of half polypous, utterly alien entities... They were only partly material and had the power of aerial motion, despite the absence of wings... [They exhibited] a monstrous plasticity and ... temporary lapses of visibility... [S]ingular whistling noises and colossal footprints made up of five circular toe marks seemed also to be associated with them.
—H. P. Lovecraft, "The Shadow Out of Time"
