MOONBEAST
“For they were not men at all, or even approximately men, but great greyish-white slippery things which could expand and contract at will, and whose principal shape - though it often changed - was that of a sort of toad without any eyes, but with a curious vibrating mass of short pink tentacles on the end of its blunt, vague snout.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

“It was a paw, fully two feet and a half across, and equipped with formidable talons. After it came another paw, and after that a great black-furred arm to which both of the paws were attached by short forearms. Then two pink eyes shone, and the head of the awakened gug sentry, large as a barrel, wabbled into view. The eyes jutted two inches from each side, shaded by bony protuberances overgrown with coarse hairs. But the head was chiefly terrible because of the mouth. That mouth had great yellow fangs and ran from the top to the bottom of the head, opening vertically instead of horizontally.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

DHOLE/DOEL/BHOLE

H. P. Lovecraft & E. Hoffmann Price, Through the Gates of the Silver Key

“Now Carter knew from a certain source that he was in the vale of Pnath, where crawl and burrow the enormous bholes; but he did not know what to expect, because no one has ever seen a bhole, or even guessed what such a thing may be like. Bholes are known only by dim rumour from the rustling they make amongst mountains of bones and the slimy touch they have when they wriggle past one. They cannot be seen because they creep only in the dark.”
H. P. Lovecraft, The Dream-Quest Of Unknown Kadath

COLOURED GAS BEING
”He had learned much of the Other Gods in distant parts of space, especially in that region where form does not exist, and coloured gases study the innermost secrets. The violet gas S’ngac had told him terrible things of the crawling chaos Nyarlathotep, and had warned him never to approach the central void where the daemon-sultan Azathoth
gnaws hungrily in the dark.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

DOG-LIKE MOUNTAINS
“For the mammoth bobbing shape that overtopped the ridge was only a head—a mitred double head—and below it in terrible vastness loped the frightful swollen body that bore it; the mountain-high monstrosity that walked in stealth and silence; the hyaena-like distortion of a giant anthropoid shape that trotted blackly against the sky, its repulsive pair of cone-capped heads reaching half way to the zenith.”

“And straight in the rear were three of the mighty mountain shapes seen full against the southern stars, tiptoeing wolf-like and lumberingly, their tall mitres nodding thousands of feet in the air. The carven mountains, then, had not stayed squatting in that rigid semicircle north of Inganok with right hands uplifted. They had duties to perform, and were not remiss. But it was horrible that they never spoke, and never even made a sound in walking.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

URHAG
”High over its jagged rim huge ravens flapped and croaked, and vague whirrings in the unseen depths told of bats or urhags or less mentionable presences haunting the endless blackness.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

HUNTING HORROR
“And hoary Nodens raised a howl of triumph when Nyarlathotep, close on his quarry, stopped baffled by a glare that seared his formless hunting-horrors to grey dust.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

“And in the air about him were great viperine creatures, which had curiously distorted heads, and grotesquely great clawed appendages, supporting themselves with ease by the aid of black rubbery wings of singularly monstrous dimensions.”
H.P. Lovecraft & August Derleth, The Lurker At the Threshold

VOONITH
“And all through the night a voonith howled distantly from the shore of some hidden pool, but Carter felt no fear of that amphibious terror, since he had been told with certainty that not one of them dares even approach the slope of Ngranek.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath

GHAST
“…the ghasts, those repulsive beings which die in the light, and which live in the vaults of Zin and leap on long hind legs like kangaroos.

After a moment something about the size of a small horse hopped out into the grey twilight, and Carter turned sick at the aspect of that scabrous and unwholesome beast, whose face is so curiously human despite the absence of a nose, a forehead, and other important particulars.”
H.P. Lovecraft, Dream-Quest Of Unknown Kadath
