An adoquin is a velvet cobblestone wall with two bulbous eyes and a massive grinning mouth in the middle that spans vertically from the top to the bottom of the wall. The mouth is a like a big pocket where the adoquin puts its dead victims. It has two long flaky arms with big thin claws that it uses to grab. It likes to take a hold of people and hold them up to one of its eyes, then blast them at point-blank range. It walks on hundreds of small insect-like legs that protrude from all four sides of it. It is surprisingly light and can move faster than one would imagine. 

It puts its victims into its mouth and takes them to its flesh pile, its most treasured possession. A flesh pile is a hoard of dead bodies located where the adoquin calls home. An adoquin seeks nothing but to grow its flesh pile with creatures of different species. An adoquin gets distressed when its flesh pile starts to decompose and it desperately tries to collect replacement corpses of the same exact species. If the new horde is smaller than it was previously, the adoquin gets enraged and goes on a day long hunt to grow the pile. It calms down if it finds enough bodies to satisfy it. 

An adoquin uses the blood of its victims to paint its nest red. It then uses the colour to camouflage itself as a dead end by closing its eyes and mouth and hiding its arms in its mouth. When it can hear a creature it attempts to scare them and chases after them while shooting its eye beams and wildly snatching at them. 

Adoquin live in caves and mountains where they find holes that they fit through. They like to dwell in long tunnels where they can rush towards intruders.
