Death-Vines of Xiclotl

Large, carnivorous, intelligent, purple flowers with tentacles. They are able to launch their seeds with enough force to reach space, and subsequently land upon distant worlds throughout the galaxy.

Shantaks

Like Byakhee, Shantaks are typically treated as mounts. Unlike the Byakhee, however, Shantaks are not very intelligent, so are more suited to the role. Also like Byakhee, Shantaks can fly through space. They are described as being larger than an elephant with a head like a horse's. Despite also being referred to as a "Shantak-bird", they have scales instead of feathers.

Lloigor

Lloigor are invisible, reptilian beasts, though they can create visible forms if needed. In the past they have enslaved humans and used torturous means to keep them in line. The remaining Lloigor now reside under the earth and sea.

Spawn of the Green Abyss

One of the many amorphous creatures of the Mythos, the Spawn of the Green Abyss are aquatic by nature, intelligent, and have the ability to hypnotise victims with a song.

Flying Polyps

As with the image below, Flying Polyps are generally rendered as buoyant, cancerous monstrosities. They live in caverns below the ground, are able to command the winds, and are able to turn invisible at will—though they naturally fade in and out.

Chthonians

Chthonians are giant burrowing worms—though not as large as Dholes—with tentacles for a "head". They are telepathic and can create earthquakes at will.
