Hollyrock-a-Bye Baby is an animated feature length film based on the 1960s series classic, The Flintstones. It first aired on ABC on December 5, 1993. It is the sequel to I Yabba-Dabba Do! and is followed by A Flintstone Family Christmas, which aired less than two weeks later on the same channel. The movie has been reaired on Cartoon Network and Boomerang, usually as part of Mother's Day special programming.


The Flintstones and the Rubbles go to Hollyrock to visit their children, Pebbles and Bamm-Bamm---who's trying his luck at being a screenwriter---after Pebbles reveals that she's pregnant with her and Bamm-Bamm's first baby. During the visit, the parents drive their kids crazy by telling them what to do now that they're going to be parents, even though Pebbles and Bamm-Bamm can obviously take care of themselves. Meanwhile, Fred and Barney help Bamm-Bamm sell his script, but end up in a mess with a robbery of a giant pearl when it's mistaken for a bowling ball. Big Rock sends his henchmen Rocky and Slick to recover the giant pearl. Fred and Barney manage to get the tickets to a taping of a show at ABC studios in hopes to sell Bamm-Bamm's script. Fred and Barney encounter Shelley Millstone in hopes to have her for Bamm-Bamm's film. It doesn't go well and the security guard is called in to eject them. A chase begins throughout the ABC studios and they eventually get thrown out.

Meanwhile, Wilma and Betty are helping Pebbles design a nursery for the baby when Pebbles reveals that she's attending the premiere of "It Came From the Tar Pits" starring Craig Craigmore. Fred and Barney decide to take the advantage by finding someone to take the screen. Rocky and Slick also slip in to get to Shelley Millstone who attempt to get the giant pearl, but Bamm-Bamm mistakes Slick and Rocky for movie producers. When they find Fred's car, they are attacked by Dino. Back at the party, Fred tries to get to Shelly Millstone, which ends up with Craig Craigmore injured. The next day, Pebbles has to work late, so she asks her father to take her place at her Lamaze class.

With Bamm-Bamm exhausted, Barney attends in Bamm-Bamm's place. Slick and Rocky follow Fred to the baby training seminar where Slick and Rocky infiltrate the class. It soon breaks up into a fight which ends up with Fred, Barney, Slick, and Rocky being thrown out. After a call from Rocky, Big Rock gets impatient and decides to take over the operation. Pebbles and Bamm-Bamm begin fearing that they aren't ready to have kids, as they're very busy with other things. Fred and Wilma try to get Pebbles to calm down when she starts to blow her top because they're driving her crazy. Wilma and Fred barely notice what they're doing until Pebbles cries that they're treating her like a baby, telling her what to do and giving her unpleasant surprises. The next day, Pebbles attends a baby shower which her grandmother, Pearl, also attends and starts treating Wilma the way Wilma had treated Pebbles. Pearl sends Fred and Barney to get the baby supplies. At the grocery store, they end up gaining a lot of "Maps to the Stars' Homes" and decide to take another shot at Shelly Millstone.

Later that night, Fred and Barney sneak into Shelly's property and distract the guard dogs. Rocky and Slick show Big Rock the house where Fred and Barney are staying and mistake Pearl for Fred when they abduct her. The next morning, Fred confesses to Bamm-Bamm that he lost the script in Shelley Millstone's yard. They soon return a call from Big Rock who demands the giant pearl in exchange for Pearl's freedom. They are forced to give them the pearl for the exchange. They disguise a bowling ball as the pearl when they forget the giant pearl.

Pebbles goes into labor and they drive a bus towards the hospital with Big Rock, the real bus driver, and the painter of the bike the bus driver borrowed. There is a high speed chase which attracts the local cops. Fred finally makes it to the hospital and Pebbles is taken into the hospital fast. Big Rock, Rocky, and Slick catch up to them and Bamm-Bamm arrives to take them down as the cops arrest the crooks. Pebbles ends up giving birth to boy-girl fraternal twins. The baby boy looks like his father and has red hair like his mother. The baby girl looks like her mother and has white hair like her father. When the babies are taken home, the baby girl proves to have muscular strength like her father, and Pebbles suggests they name her "Roxy". Roxy's brother proves to have a loudmouth just like his Grandpa Flintstone because he's another chip off the old Flintstone. That's when Bamm-Bamm suggests they name him "Chip".

Mr. Pyrite calls to tell Pebbles that Craig Cragmore loved her idea and wants her to do all his movies, and Mr. Pyrite even gives Pebbles a promotion for this. She almost turns it down when Wilma admits that everything she said was wrong and convinces her daughter to accept the promotion, and Pebbles accepts the promotion. Shelly Millstone arrives with Bamm-Bamm's script, and he allows her to star in his film. Fred and the others head back to Bedrock, leaving their children and grandchildren in happy harmony.
