Check out the migo thinker from our new Sandy Petersen’s Cthulhu Mythos for Pathfinder 2nd Edition, which you can now purchase in PDF format.

Migo thinkers have been engineered to maximize their ability to calculate and to solve problems. Their central bodies resemble bloated brains, which are actually sensitive vibration receptors. A migo can sense nearby motion through vibration and air movement.

What you see. This hideous crustaceous creature possesses multiple jointed limbs extending from its carapace and folded, fanlike wings. Its head is a brainy protuberance covered with tiny bristles that constantly cycle through a nauseating array of clashing colors.
