Gigantic Vermin are abnormally large vermin which roam the chambers underneath the Temple of Styx.
Gigantic Vermin will chase Zagreus when he is spotted by one. If close to him, they will attempt a fast melee bite attack in his direction.
Gigantic Vermin will also stop moving to occasionally create puddles of Styx Poison around them. These puddles will vanish after a short time, or if all the enemies in a room have been defeated.
There is a mini-boss variant of the Gigantic Vermin which has heavily increased armor and health, and has jet-black colored fur instead of its usual gray fur. It moves slightly faster than a typical Gigantic Vermin, and the Styx Poison puddles it creates are larger and last for longer periods of time.
