Plot synopsis:
Pebbles Flintstone, who now works for an ad agency and Bamm Bamm Rubble, who works in a car repair shop, decide to get married after Bamm Bamm proposes with a poem, in the middle of the street (ironically after Pebbles mistakenly thinks he was trying to dump her when Bamm Bamm read her a letter that started "Dear Pebbles"). However, Fred has lost money when he bet his nest egg on his team, the Bedrock Brontos. Fred tries to ask for a raise from Mr. Slate, only to lose 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. Meanwhile, Wilma's mother Pearl Slaghoople arrives to help with the wedding. Pebbles and Bamm Bamm decide to get married 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. Reconciling with Barney, Wilma and Betty, 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. 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. At the end, Pebbles and Bamm Bamm reveal they are moving to Hollyrock with Barney paying their way with his Rock Vegas winnings, at which Fred gets angry with Barney and they start to fight again as Pebbles, Bamm-Bamm, Wilma and Betty try to stop the argument.

Review: Perfect title, AMAZING movie, and equally incredible as the iconic live action film.. Ignore the laughably clueless crybaby and his troll-worthy excuse for a "review". This highly enjoyable story is easily the single best iteration of The Flintstones EVER, with the first live action movie starring John Goodman being an extremely close second.Great voice acting, great story, great emotional moments, great laughs. The end.Actual facts for a change, you're welcome ; ). Horrible title, OK movie. (And miles better than the live-action version.). Unlike most cartoon characters, Pebbles Flintstone and Bamm-Bamm Rubble got to age with subsequent appearances; born and adopted respectively during the original series, and stars of their own spinoff (one of several) in the 1970s, the redhead and the hunk have reached adulthood by the time of "I Yabba-Dabba Do!"Just as "The Flintstones" was a standard sitcom in animated form, so this TV movie is a standard comedic example of it; Pebbles and Bamm-Bamm are finally about to get married, but Fred doesn't want this to happen on account of his not being able to pay for it (he lost the Flintstone nest-egg gambling)... cue mildly amusing shenanigans, a subplot about gangsters that combined with a climax in Rock Vegas brings the film dangerously close to "Sister Act" territory, a bit too much gooeyness, and a horrible title song. (Hearing the aging voice of Jean Vanderpyl [the only one of the original core cast still alive at the time of production] as Wilma Flintstone is additionally depressing.) Still, it passes the time easily enough, and it certainly beats those Bedrock Cops cartoons.(Note to "Will & Grace" fans: Megan Mullally supplies the voice of Pebbles. High-pitched even then.)
