One day, while at a department store, Dicky begged his father to buy him a famous robot toy called CJ1. Ti cannot afford to pay, and the situation ends badly when Ti hits a stubborn Dicky in front of other customers. Dicky finds solace in Miss Yuen, who is passing by. That evening, Ti goes to the junkyard, where he usually picks up household items and clothes for Dicky. He finds a strange green orb left behind by a space disk and takes it home, telling Dicky it is a new toy. He hesitated at first, but then accepted. The next evening, the blue orb transforms into a cute and adorable dog-like alien creature, befriending Dicky. After playing with the alien, he learns that it has the ability to recover from a rotten apple that fell to the ground. Dicky is delighted and names the alien “CJ7”.
