2060. Elaine Silver and Melanie Silver as Pebbles Flintstone

Pebbles Flintstone (also known as Pebbles Flintstone-Rubble as an adult) is a fictional character, the red-haired daughter of Fred and Wilma Flintstone. She is most famous in her infant form on the animated TV show The Flintstones, but has also appeared at various other ages, including as a teenager on the early 1970s spin-off The Pebbles and Bamm-Bamm Show and as an adult in three made-for-television movies. She spent most of her time with her best friend and later husband Bamm-Bamm Rubble whom she affectionately nicknames "Bammer."
Pebbles dwelled in the fictional prehistoric city of Bedrock, a world where dinosaurs coexisted with barefoot cavepeople and the cavepeople enjoyed "primitive" versions of modern conveniences such as telephones, automobiles and washing machines.
