Biography
Peter Puppy turns into a large monstrous dog whenever he is hurt, mad or scared. This trait is very similar to that of Dr. Bruce Banner as the Hulk. While he is in his monster form, he will attack Earthworm Jim or anything that resembles him (as seen when he once attacked Psy-Crow, who was disguised as Jim at the time). After a short while he transforms back to his cute normal form.
