Lost In Space Penny Robinson

Penny Robinson of Lost In Space is the middle child of the Robinson family. She spent a large amount of her time on the show keeping her little brother Will out of trouble. She is quite different than her two blond haired, blue eyed siblings (Will and Judy Robinson) as Penny has dark hair and deep brown eyes.

Penny Robinson is only eleven years old when the Juniper II becomes lost in space. Through three seasons we watch as Penny grows up. She developed a crush on the second in command, Don West. She acquires a pet named Debbie which looks like a chimp and can only chirp the word bloop. Penny Robinson is played by Angela Cartwright, a child actor in the fifties and sixties.
