Porco, the pig, is a good and lovable young piglet who lives in the animal-inhabited town of Animaltropolis with his large family and his best friend Cody, the cat. He loves his life and has several good qualities.

The only strange thing about Porco is that he loves spaghetti! The problem here is that his mother only knows how to make slop, and thus that is all she ever feeds him and his siblings. So, who knows when Porco will be able to eat that delicious meal of noodles, tomato sauce, and meatballs again?

One day while walking home from school, Porco notices a special sign in the window of Mrs. Chicken's Restaurant: "All-You-Can-Eat Spaghetti and Meatballs!" This is Porco's big chance to have more of his favorite food! But the question is, How much can he eat before he's through? Will he go too far?
