Hollyrock-a-Bye Baby is an American animated made-for-television film based on the original series, 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.


After Pebbles and Bamm-Bamm get married and move to Hollyrock in I Yabba-Dabba Do!, Fred and Barney are both working overtime for Mr. Slate, and Wilma and Betty Rubble now own a food delivery service called 'Bone Appetite', but much to Fred's disgust, Wilma is not there to cook for him, he cooks his own TV dinners as well as Barney's.

One day, the Flintstones and the Rubbles go to Hollyrock to visit their children, Pebbles and Bamm-Bamm (who is trying his luck at being a screenwriter), after Pebbles reveals that she and Bamm-Bamm are going to have a baby. During the visit, they drive Pebbles and Bamm-Bamm crazy by telling them what to do now that Pebbles is going to have a baby.

Meanwhile, Fred and Barney try to help Bamm-Bamm sell his script, but end up in a mess with a robbery of a giant pearl when it is mistaken for a bowling ball. The villainous boss, Mr. 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 Rocky and Slick 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 Fred attend a Lamaze class while she does paperwork for her boss, Mr. Pyrite.

With Bamm-Bamm exhausted, Barney attends in Bamm-Bamm's place. Slick and Rocky follow Fred to the Lamaze 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 declare themselves unready for the baby after they were busy. Fred and Wilma try to get Pebbles to calm down until she breaks down in tears. The next day while Fred apologizes to Pebbles about being too helpful, she attends a baby shower which Wilma's mother Pearl also attends. 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 gives birth to twins, Roxy (who has muscular strength like her father) and Chip (who has his Grandpa Flintstone's mouth because he's another chip off the old Flintstone).

As for Bamm-Bamm's script, Shelly Millstone got Bamm Bamm's script when Fred and Barney left it to her house. She loves the script and wants to star in it and Bamm Bamm sold his screenplay. Mr. Pyrite manages to get the script to Craig Craigmore and promotes Pebbles as Vice President. Fred and the others head back to Bedrock, leaving their children and grandchildren in happy harmony.
