I Yabba-Dabba Do! is a 1993 American animated made-for-television film based on the 1960s series, The Flintstones and its spin-off, The Pebbles and Bamm-Bamm Show. It premiered on ABC on February 7, 1993.

Plot
Pebbles, who now works for an ad agency and Bamm-Bamm, who works in a car repair shop, decide to get married after Bamm-Bamm proposes with a poem, in the middle of the street (after Pebbles mistakenly thinks he was trying to dump her when Bamm-Bamm read her a letter that started "Dear Pebbles"). However, Fred loses the family savings when he bet it on his team, the Bedrock Brontos. Fred tries asking for a raise from Mr. Slate, but is dismissed from his job because of his violent temper.

Fred enlists Barney's help in bringing more money for the wedding, but they fail, losing Barney's money to a real estate con artist and becoming more in debt than before. Meanwhile, Wilma's mother Pearl Slaghoople arrives to help with the wedding. Pebbles and Bamm-Bamm decide to elope in Rock Vegas because of their parents' arguing and fighting. Wilma and Betty discover the truth about Fred and Wilma's nest egg, and Fred is forced out of the house. After seeing that even Dino’s mad at him, Fred finally realizes the error of his ways and decides to fix his mistakes. Reconciling with Barney, Wilma, Betty and Pearl, Fred asks Barney to help search for Pebbles and Bamm-Bamm.

Fred and Barney travel to Rock Vegas looking for Pebbles and Bamm-Bamm. They stop at a casino where Barney wins more money. They are attacked by the Wedding Whackers gang after mistaking them for Pebbles and Bamm-Bamm getting married and took a photo of them robbing a newlywed couple. Shortly afterwards they are rescued by Pebbles and Bamm-Bamm. During the chase, the photo of the Wedding Whackers is destroyed, so the four are captured as suspects of being the marriage whackers, along with the real marriage whackers.

While in detainment, Fred reveals all the trouble he has gone through to try to help Pebbles with her wedding ceremony which leads the marriage whackers to reveal to their crimes, to the dismay of the Whackers' mother. Since Barney made a lot of money on his casino wins on the big wheel, they can use it to pay for the wedding, replace their nest eggs and pay off their debts. Fred, Barney, Pebbles and Bamm-Bamm finally reunite with Wilma, Betty and the others. Mr. Slate rehires Fred, and Pebbles and Bamm-Bamm get married, with Fred, Barney, Dino, Wilma and Betty as the happy ones seeing them getting married. Fred gets his job back from Mr Slate and is given a raise after being invited to the wedding. At the end, Pebbles and Bamm-Bamm reveal they are moving to Hollyrock with Barney paying their way with his share of the Rock Vegas winnings, at which Fred gets angry with Barney and they start to fight again.

Trivia

 * The sequel, Hollyrock-a-Bye Baby, is very difficult to syndicate and the attempt of releasing it on home video was delayed for nearly two decades. It was seen once on Cartoon Network and its sister channel Boomerang as part of Mother's Day special programming in the early 2000s. However, it is not available on the Boomerang app. This is mainly due to the suggestive material, including Pebbles mentioned that she got "really busy" with Bamm-Bamm and scenes showing pregnant women practicing giving birth, as the executives felt that these subjects are just too "full-on" for the attended audiences.
