holidays at a camp. At first the children enjoy carefree days amidst unspoiled nature far away from adult supervision. But their life changes dramatically when they come across what they believe to be a small dog, badly in need of help. The creature - known as Pochi - turns out not to be a dog at all but an alien on an important mission. It seems there is a mysterious substance on earth that is coveted throughout the universe. Pochi had almost found it but was so badly injured during a fight that he had to give up his search. Thanks to the children's help, the alien survives - and decides to reward them generously. "Where would you most like to travel?" is the question Pochi puts to his rescuers. Their answer is prompt, if vague: "As far as possible!"

During the course of their travels they discover that the substance coveted throughout the universe is in fact also integral to Japanese cuisine - and it just so happens that one of the kids has some of this mysterious substance in his pocket.
