[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"
The Flying Polyps were banished to their underground cities and trapped there by the Great Race of Yith.
