Danny is an older mamodo than Zatch whose book owner and father is Mr. Goldo, and the two are protecting a precious work of art. Meanwhile, Kiyo is telling Zatch about the work of art and describes it as Zatch's equivalent of a ten-foot yellowtail with dipping sauce. As he and Ponygon go to see the statue which is really being shown two days later, they have an uncomfortable run-in with Danny, thinking Zatch was sneaking up on him. But when everything is sorted out, they become friends. Then they come to see the statue, only to find Mr. Goldo tied up and the art gone. Apparently the people the staue was given to was a gang, so Zatch, Mr. Goldo, and "Danny Boy" as Goldo called him go to a boat to retrieve it. Ponygon is sent home to tell Kiyo the situation when he gets home, but he did not make sense of course and the note Zatch left was very vague. At the boat, Danny was discovered by Zatch to have a self-healing power, but it comes to no use when Mr. Goldo was held at gunpoint. Just at the nick of time, though, Kiyo bursts in to the right boat after accidentaly looking in on a girl dressing and makes Zatch blast the gun out of the gang boss' hand. All seemed well after that until the boss escaped from the police's hands and almost tumbles a truck on the car with the statue and Danny's book. But Danny shows bravery and loyalty to his book owner by catching the truck load before it hits the car. Danny asked Zatch to blast the load of apparently gasoline as a friend, so he could save the statue and prove himself worthy. So once again Zatch puts down another newly-found friend, like Kolulu. While Danny's book is burning Mr. Goldo shows pride in his mamodo by calling him his son and his real name instead of "Danny Boy".
