In a far away place a super secret program from the Snack world conducted experiments on young snacks from different nations. Its objective? Create the perfect fighter. The results would be terrifyingly efficient: The test objects would destroy the facility and escape. Some to obtain freedom, others to achieve their goals, and one of them to stop the others, and prevent them from doing the Snack Attack on the rest of the world. These would become known as the Yummies Fighters.
