A few days ago I posted the following in Flintsones Season 3 review thread: Since no one responded to my question earlier I decided to do some digging of my own regarding the opening sequence. I found an old tape I recorded from TV containing "VENTRILOQUIST BARNEY"(an early Pebbles episode)and YES it has the opening I remember. Pebbles is playing with toys called BUILDING BLOCKS and Fred pick her up runs out of the house. This sequence has No Rubbles and No Bamm Bamm. So it looks like all the episodes after "Dress Rehearsal" have the wrong opening sequence on the DVD set which is disappointing. I think I even heard some one mention that one episode has the later season's Rubbles and Bam Bam sequence! However there still is hope for Season 4. The tape I have also contains "Ann Margrock Presents" and it apparently still has the Pebbles solo sequence (since Bamm Bamm comes a few episodes later). Hopefully someone can bring this to Warner Bros.' attention so we can enjoy this sequence in early season 4 at least. I know that Warner Bros. is currently trying to find all the original bumpers for the Yogi Bear and Huckleberry Hound cartoons which shows they truly care about the original viewing experience. Perhaps things can get rectified for season 4? Now it's also possible the Pebbles sequence was added later for syndication and I may be wrong about this (if there's a hardcore Flintstones fan out there who knows please reply.) If that's the case perhaps they can show it as a bonus feature for season 4?.
