The soft, boneless cranium of the Crepugnant acts as a powerful neural antenna, constantly broadcasting its unique cognowaves to other psychocompatible monsters. This signal hyper-sensitizes other beings to external stimuli with special focus on the Crepugnant itself, triggering uncontrollable terror and revulsion in those who perceive its finely writhing, squelching facial features. Even the soft, moist sound of its seething feelers and suckers can instill an escalating feeling of impending doom, and the lightest physical contact with its wet, twitching flesh can send affected individuals into blind panic.
