Supercow

Life on the Farm in Sunny Valley was just great until the evil professor Duriarti escaped from prison! The heartless bad guy's first act was to seize the farm and take all of its inhabitants hostage to conduct hideous experiments on them.

Supercow caught wind of his dastardly deeds. Resolute and merciless to all the evil in the world, Supercow immediately set off to help the poor residents of Sunny Valley.
