Carbon Dog

Carbon Dog is the 8th and final Sanctuary Boss fought in EarthBound. It guards Fire Spring, the last Your Sanctuary location in the game. Carbon Dog can't use PSI during this stage. Carbon Dog's attacks include spewing a fireball, which is a regular fire attack, making a piercing howl that has no effect, using a low level bite attack, shooting out a spray of fire (PSI Fire Ω), and to charge forward, which is a high level attack. After being defeated, Carbon Dog immediately turns into Diamond Dog.
