Infant zuipnyrns have a soft, malleable, spherical, furry body with a single eye stalk and a jawless, toothless mouth. As they age, zuipnyrns can grow all kinds of organs in order to adapt to their environment. A zuipnyrn's eye stalk can emit a blinding flash of light or a hypnotic aura that it uses to avoid fights, persuade others into helping it escape, or cause them to feel instinctually obligated to raise a young zuipnyrn as their own child.
