Grog

Grogs are a sessile lifeform, spending most of their lives attached to a rock from which they catch prey using their extremely long tongue. The young of the species are motile, the female being described as something like a hairy bulldog and the male approximately the size of a chihuahua. Both possess serrated cutting edges instead of teeth. After mating, they search out a suitable location in which to settle and become sessile adults. The sessile adults appear as a furry cone roughly 5 feet (1.5 m) high by 4 feet (1.2 m) wide at the base with a bald, rounded point and a reddish coloration similar to the sands of their environment. They possess four small hairless vestigial paws, a 3-foot (0.91 m)-wide mouth and no eyes.

It was since discovered that they were indeed sentient and furthermore possessed telepathic abilities which they used to control prey animals, literally making them leap into their mouths. It is implied that Grogs are aware of human fears and are careful to appear friendly and benevolent.
