I Yabba-Dabba Do! is a made-for-TV animated film based on the original series, The Flintstones and its spinoff, The Pebbles and Bamm-Bamm Show. It premiered on ABC (the same network the original series was aired) on February 7, 1993. The telefilm had a relatively high level of animation quality.
The televised feature received mostly negative reviews from critics. One of them, in the Los Angeles Times, concluded with the words "YABBA DABBA DON'T".
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"). Although Pebbles and Bamm-Bamm agree to have a simple wedding, Fred would rather spoil his daughter by giving her a fancy wedding and hosting a bachelor party for Bamm-Bamm. The trouble is that he 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, but his short temper causes him to get fired.
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 feels overwhelmed with having a big wedding, and she would rather keep it simple. Fred wants to cancel the wedding because of an incident at Bamm-Bamm's bachelor party. Miserable with their parent's fighting, Bamm-Bamm and Pebbles decided to get married in Rock Vegas despite knowing about the Rock Vegas wedding whackers. But after they leave, Barney drops the bomb about Fred and Wilma's nest egg much to Wilma's shock and anger. Fred is evicted from the house after being physically abused by Wilma and her mother and apologizes to Barney, Wilma and Betty before he enlists Barney's help searching for Pebbles and Bamm Bamm.
Fred and Barney go 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 breaks, so the four are arrested as suspects of being the marriage whackers, along with the real marriage whackers.
While in jail, Fred tells all the trouble he's gone through to try and give Pebbles a nice wedding which leads the marriage whackers to confess to their crimes, to the chagrin of the Whackers' mother. Fred, Barney, Pebbles and Bamm Bamm finally return to Wilma, Betty and the others. Mr. Slate rehires Fred, and Pearl and Wilma apologize to Fred for the mistake they made and the abuse they gave him. Pebbles and Bamm Bamm get 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 argue as the film ends.
The television special received generally negative reviews. It received two out of five stars from TV Guide, noting that the film was " tolerable, but overlong, animated feature based on the venerable 1960s cartoon series." A film critic for the Los Angeles Times ended with the review saying; "YABBA-DABBA-DON'T." The film received a 58% from review aggregator Rotten Tomatoes.
