CLASS: Bioconstruct.

  This timid monster hides itself in its own massive, external skull, protecting a fragile pink body with devastating pyrokinetic powers. It is actually able to telepathically transmit heat itself, literally frying the brain of an attacker if it so desires.

 The seam of its skull heals completely every night, and a fresh one must be cut by a single triangular tooth on the end of its tongue. It makes a cry much like a barn owl.
