Synopsis by Hal Erickson
Harold J. Stone makes his first appearance as intergalactic showman, Farnum B, who wastes no time capturing the Robinsons so he can exhibit them in his traveling zoo. Escaping from his cage, Will (Billy Mumy) passes through a time warp with the redoubtable Farnum B one step behind him. Meanwhile, back on the planet, Dr. Smith (Jonathan Harris) takes charge of the zoo, appointing as his second in command Farnum B's long-suffering caveboy assistant Oggo (Gary Tigerman) -- who has a crush on the imprisoned Penny (Angela Cartwright).
