We, my family and I, began playing this game in about 1987. Each enemy looked to us like a certain type of animal. The name "Hungry Mutant Animals" was chosen for that reason.
The storyline? Well.... In a field far far away, in a time still to come, old farmer Joe was developing a super strength formula for his farm animals. When it came time to feed them his newly finished formula, his farm hand made the mistake of mixing in too much vitamin C. During the night all the animals mutated into hungry beasts. Now it is up to farmer Joe and his farm hand to stop those animals before they conquer the world!
