The premise of the Katamari franchise sounds downright frightening. The King of All Cosmos orders his son, the pint-sized Prince, to roll around a ball that sticks to anything smaller than it, growing in size until it's eventually rolling up entire cities in seconds. Screaming children, animals, trash cans - they're all added to the giant mass, which is eventually devoured by the flamboyant King and turned into a star. Literally. He eats the mass of people and turns them into a freaking star.
