Pebbles Flintstone-Rubble is a fictional character in the Flintstones franchise. The red-haired daughter of Fred and Wilma Flintstone, Pebbles is born near the end of the third season. She is most famous in her infant form on 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 television films. She spent most of her time with Bamm-Bamm Rubble, her childhood best friend whom she eventually marries.^[11]

According to the February 22, 1963, edition of TV Guide, Pebbles was born at the Bedrock Rockapedic Hospital on February 22, 10,000 BC. That particular year was never actually cited within the show itself; most versions of the show put the Flintstones' era as around 1,000,000 BC.^{[citation needed]}

As an infant, Pebbles quickly became lifelong best friends with her next-door neighbor, Bamm-Bamm Rubble.^[12]

As a pre-teen, Pebbles was an excellent baseball player, which led to a misadventure involving her father, as seen in the 1978 primetime special The Flintstones: Little Big League.^[13]

By the time she was a teenager, Pebbles began dating Bamm-Bamm and was noted for getting their friends into various misadventures, mostly due to sharing her dad's penchant for schemes that would inevitably backfire (such as causing a strike by Bedrock's city employees when she was elected honorary mayor for a week^[14]). Her friends and she attended Bedrock High School; Pebbles had a catchphrase similar to her father's: "Yabba-Dabba-Doozie!"^[15]

As an adult, Pebbles pursued a career in advertising and married Bamm-Bamm.^[7] After this, the newly married couple moved to Hollyrock, a fictional, prehistoric version of Hollywood, California. They eventually had a son named Chip and a daughter named Roxy, who were fraternal twins.^[11]

Through the various Flintstones incarnations, the age of Pebbles has varied widely, appearing as an adolescent in one spin-off and as an infant again in the next. Arranged roughly in chronological order, the Flintstones incarnations in which Pebbles has made appearances are:

In 1963, when Hanna-Barbera decided to add a baby to the show, their first choice was a boy. When Ideal Toy Company heard this, company executives approached Hanna-Barbera with a proposal to change the baby character to a girl for which the toymaker could create a doll, and Hanna-Barbera agreed.^{[citation needed]}

Pebbles, in her conventional toddler incarnation, is sometimes seen in the various Post Fruity Pebbles and Cocoa Pebbles cereal commercials that have been produced over the years. Pebbles also appears on the packages of "Flintstones" children's vitamins and with Bamm-Bamm on the packages of "Flintstones" toddler vitamins, which are manufactured by Bayer Healthcare (formerly Miles Laboratories).
