All You-Can-Eat Meatball Day came just once a year. George had been waiting all month for that day, a day almost bigger than his birthday! On Meatball Day, George helped his friend, Chef Pisghetti, cook some delicious meatballs and serve them to the hungry crowd. But this year, the crowd had vanished! Something was keeping people away... something pretty big. And that something was Phinneas T. Lightspeed and his speedy Meatballs-o-Matic machine. In despair, Chef Pisghetti vows to cook no more. Determined to help his friend, George goes on a mission to enter the Chef's meatballs in the world-famous Golden Meatball Contest in Rome.
