(I do not know who posted the original picture, I just know I love this thing. I’ll make my own lore on it)

Grolms (or Rockbellies) are ancient, cycloptic, bipedal cryptids said to reside in just about anywhere that isn’t densely populated whit humans. They have been found in all types of biomes around the world.

Witness statements describe them as small (usually a foot in length), smooth skinned, hairless cyclopses with big lipped mouths that form a bored deadpan expression. They bury themselves into ground in order to be confused with rocks—their feet may stick out if done wrong, they also hide among rocks and wherever they can fit themselves.

Their colors range from all sorts of greys to light black. Some people have stated they can switch colors depending on the typical color of rocks where they live, but this is still word of mouth so take it with a grain of salt.

Much of them remains unknown: their origin, reproduction cycles (if any), development, their eating habits, and how their bodies function since they are so rare and even harder to catch.
