Brothers Louie and Ralphie Ratso want to be tough, tough, tough like their dad, Big Lou. But every time they try to show that they are, they end up by accidentally doing good deeds.

Logan, Miles, Philip, and Daisy have the chance to go on tour to promote their new candy and they each have very different reasons for hitting the road. The stakes are a lot higher than they thought, however, and a decades-old secret is revealed. The four friends embark on a journey full of hidden treasures, imaginary worlds, rivers of light, a map of awe, a sky of many colors, and one very small cat who thinks he's a dog.
