Ep 12. A Day at the Zoo

Don, Judy and Penny venture out to collect rock and plant specimens. Penny, on her own, stumbles into a net trap! There she learns she's been trapped by Farnum B, owner of an intergalactic zoo, who intends to capture all of the Robinsons and put them on display. For Doctor Smith, this is an improvement, since Farnum's technology gives him everything he wants! But when Farnum's assistant Oggo strands Farnum on a distant planet, Smith takes over. He plans to run the zoo, still using the Robinsons as exhibits!
