A three-part episode introducing new key elements of the series. After failing to open diplomatic relations with Ophiucius, Rocky is on his way back to Earth aboard the Orbit Jet when he spots a space anomaly that causes him to alter course--a pair of "Gypsy Moons," wandering the galaxy linked together by gravity and an atmosphere chain. He moves in to investigate and discovers that the two moons are inhabited. One is called Posito and the other Negato--landing on Posito, he finds a race of highly verbal people, led by their ruler Vavaro (John Banner of HOGAN'S HEROES); and on Negato, a race of people who use music but not many words. After starting to learn their language, however, Rocky discovers that the people of Posito want him to help them destroy Negato, and they take Vena hostage to force him to their side. He has to find a way to change their minds and make peace between the two moons. Rocky is out of contact for so long, that he is declared lost by the Space Rangers--Cleolanta of Ophiucius, learning of this, plans to use recordings that she has of Rocky's voice in a daring plan to kidnap Secretary Drake and use him to destroy United Worlds.
