The Story

Somehow, an evil doctor named Dr. Shorizawa managed to set a trap and make both the Mighty Godzilla and the Kids' Friend Gamera, powerful and experienced kaijus, fall in it. Not only that, he reduced them to the size of a tiny mouse! And, cause of that, their fantastic powers were reduced too. To escape is not a chance.
So, to set them free again, and recover their normal status, Dr. Shorizawa ordered them to recover a precious collection of balls that he dumped by accident inside one of his evil experiments.
