When upset, copious amounts of steam pour out from the eyes of Cukoal's skull-like shell. Sometimes, the steam clouds take the shape of Cubone or Marowak before dissipating.

Its shell has taken the form of a skull to better defend itself by intimidating others. It feeds on coal to keep its internal flames strong, though the vapors and smoke it releases have stained the skull with traces of coal.

It battles using energy it gets from burning coal. It pines for the mother it will never see again.
