I Yabba Dabba Do! 1993

Pebbles, Megan Mullally, and Bamm-Bamm Jerry Houser decide to marry after a poem-driven proposal, continuing a tale of two young lovers navigating the rocky terrain of family plans and expectations. Pebbles works at an ad agency, while Bamm-Bamm holds a steady job at a car repair shop, and their decision to wed unfolds against a backdrop of warmth, optimism, and a hint of chaos. After a moment of misreading—a letter that began with “Dear Pebbles”—the couple moves forward with their plans, signaling a new chapter for their relationship and inviting the whole Bedrock community to observe.

Meanwhile, Fred Flintstone [Henry Corden] faces a harsh reality: the family savings vanish when he bets on his favorite team, the Bedrock Brontos, only to watch them lose. This setback is compounded when Fred tries to secure a raise from his boss, Mr. Slate [John Stephenson], and is dismissed because of a volatile temper that repeatedly tests the limits of patience at home and work. The financial strain deepens as Fred enlists the help of his best friend, Barney Rubble, who plays a key role in a bid to earn extra money for the impending wedding but finds himself ensnared in a separate misstep—the loss of his own funds to a real estate con artist. The mounting debt puts strain on the entire household, threatening the couple’s big day and the family’s stability.

Amid the tension, Wilma Flintstone [Wilma Vander Pyl] welcomes her mother, Pearl Slaghoople, who arrives to lend a hand with the wedding arrangements. The family dynamics grow more complicated as Pebbles and Bamm-Bamm decide to elope in Rock Vegas, spurred by the ongoing arguments between the older generation and the younger. The revelation of Fred’s financial fragility triggers a cascade of reactions: Wilma’s anger is palpable, and she insists Fred leave the house. Even Dino the dinosaur seems dismayed by Fred’s choices, signaling a deeper rift within the family. Yet this pause in harmony becomes a turning point as Fred experiences a moment of clarity and resolves to mend his mistakes.

The two couples—Fred and Wilma, Barney and Betty [B.J. Ward]—reunite with a renewed sense of purpose. Fred asks Barney to help search for Pebbles and Bamm-Bamm, and the duo heads toward Rock Vegas to salvage the wedding plans. On the way, they stop at a casino where Barney [Frank Welker] happens to win big on the big wheel, a stroke of luck that could change the wedding’s outlook. The mood shifts when the Wedding Whackers—an ominous gang—mistakenly target Pebbles and Bamm-Bamm as they document a supposed wedding on the run, capturing a photo that triggers a dramatic chase. The quartet is forced to improvise, and in a dramatic turn, Bamm-Bamm steps in to rescue Pebbles, saving the couple from a dangerous misunderstanding.

The pursuit takes them through a tense sequence where the photo of the Wedding Whackers is ruined, and the four are detained as suspects alongside the real culprits. In confinement, Fred bares the burdens he’s carried—the sacrifices, the attempts to shield Pebbles, and the sting of near-misses that have haunted him. His frank confession helps uncover the truth, prompting the Wedding Whackers’ mother to confront the consequences of her children’s crimes.

With the truth out in the open, Barney’s casino winnings are leveraged to stabilize the situation: the nest eggs are restored, debts begin to shrink, and the wedding can move forward with renewed support. Reunited with Wilma, Betty, and Pearl, the group celebrates a restored sense of community and family. Pebbles and Bamm-Bamm are wed, with Fred, Barney, Dino, Wilma, and Betty sharing in the joy of the ceremony and the successful union of two beloved young Dinosaurs.

The aftermath sees Fred reclaiming his job at Mr. Slate’s office and receiving a well-deserved raise after the wedding invitation seals a renewed trust. In a final twist, Pebbles and Bamm-Bamm announce their move to Hollyrock, with Barney generously footing their move through his share of Rock Vegas winnings. The scene closes with a touch of friction—Fred and Barney’s playful sparring resurfaces as they wrestle with family pride and the complex, endearing dynamics that define Bedrock life—and the promise of a bright, new chapter for Pebbles and Bamm-Bamm as they begin life together in a new city.
