While travelling in outer space with his parents, the dog is sent to Earth because the parents thought a fish-looking ship was going to attack them, while the strange-looking ship only asked them its way and then left. The dog was found by Gatchan while Arale, Senbei Norimaki and Peasuke Soramame were playing baseball near their residence. After it was hit by a car, the dog is healed by Dr. Goat. A few days later, the dog's parents came to Earth to get their son back.
