But success didn’t come without trouble. As with most food chains, not all of the minimum wage restaurant workers kept up with Billy Bob’s high standards of cleanliness. The result was the evolution of before-unseen species of microscopic organisms from the vats of super secret sauce. As luck would have it, a rather plump figure, with a knack for falling asleep while eating his favorite sandwich in front of the television, bought a “Mega Billy Bob” infested with super strains of these new organisms. The man’s long nap in front of the tube changed his sandwich from supper into a battleground of evolution.

Two main species evolved from the sandwich. A race of goo known as the Slime, and a group of mutated Parasites that feast upon the dead. The Slime might have chosen to live peacefully off the bounty of dung dropped by the numerous sandwich cows that have appeared, had the cows not become the Parasites’ main source of sustenance. With food becoming scarce, battle is now frequent between the races, and even between the separate colonies of each race. Chaos reigns on one of Billy Bob’s greatest creations.
