Second Season Episodes - Forbidden World (episode 33)


When the Jupiter 2 is forced to land on an alien planet, Smith is turned into a deadly secret weapon. 

Picking up the blip of a hyper-atomic missile on the Jupiter 2 radarscope, John orders Don to head for the nearest planet. Having landed, Dr. Smith, ignoring John's advice, sends the Robot out to explore the foreign terrain. When his transmission dies, Smith and Will go out after him, but they are halted by a monster, whose keeper is an alien named Tiabo.

Taking them prisoners, Tiabo divulges that his commander, General Andos, believes the Robinsons to be part of an invading force which fired a missile at the planet. The General, bearing a striking resemblance to Tiabo, tells them a secret weapon will strike the others at the spaceship. When Tiabo refuses to listen to their protests, Smith, Will and the Robot escape. When Smith throws away a jar of nectar he has been drinking, it explodes. The group realizes that the fluid -and Smith -are highly explosive.

Will realizes that Tiabo and the General are one and the same, Tiabo using a tape-recorder to project the General's voice. Tiabo confesses, explaining that he only wanted to drive them from the planet. He gives them an antidote for Smith to neutralize the explosive, which it does. 

Ray says: A very good second season episode. This episode features a dramatic crash scene where the Jupiter 2 crashes on a new planet. On this planet the Robinson's would stay for the rest of season two. If you can get past Captain Tiabo's monster Space Chicken this episode has many redeeming merits.
