7.10 60 minutes Before leaving their planet, the Robinsons meet a boy alien called J-5. They take him with them to return him to his home planet. They meet a strange ship, which turns out to be an earth ""lighthouse"" for lost ships. Thinking this ship will help them with extra fuel and star charts they celebrate, however when J-5 learns that they don't have enough fuel to take him home, he angrily sets about to destroy them all with a creation of his imagination.
