Hollyrock-a-Bye Baby.After Pebbles and Bamm-Bamm got married and moved to Hollyrock, Fred and Barney are both working overtime for Mr.Slate, and Wilma and Betty now owns a food delivery service called 'Bone Appetite', but much to Fred's disgust because she is not there to cook for him, instead he cooks his own TV dinners as well as Barneys. 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 the former reveals that she and Bamm-Bamm are going to have a baby. During the visit, they drive Pebbles and Bamm-Bamm bananas by telling them what to do now that Pebbles is going to have a baby, even though they can 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 is 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 designing a nursery when Pebbles reveals that she is 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. 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 Fred attend a baby training seminar while she does paperwork for her boss, Mr. Pyrite.
