Pyukuclops absorbs various objects into its body so that if needed, it can eject them at foes as an attack. These vomited items are covered in a mucous that attracts spirits and traps them in the item they're covered on, forcing them to possess it.

It is thought that its body is hollow with only a spectral ball of fire burning inside. It can eject its internal organs, which it uses to engulf its prey or battle enemies.
