Pebbles gets her third outfit on the show in this episode - a green shirt and white diaper.
At the beginning of this episode, Fred and Barney are watching television, which seems to be dominated by dance shows. Two of the songs heard on the television, "Roses and Rainbows" and "Dance In The Sand," were actually released by Hanna-Barbera Records' rock and roll division. The singer of "Roses and Rainbows" is Danny Hutton, who would later join Three Dog Night.
(Fred and Barney try to prove to Betty and Wilma they heard their children sing)
Fred: Laugh at us, huh, Wilma? Well, listen to this.
Pebbles: Dada Dada. Hi, Dada.
Wilma: Well, Fred? You expect "Dada Dada" to make the Top 10?
The music playing at the Hollyrock Palace entrance is actually a sped-up version of 'Rise and Shine'.
The name of the tune Pebbles and Bamm-Bamm sing, "Open Up Your Heart & Let The Sunshine In" was written by Stuart Hamblen.
Starting with this episode, the closing credits no longer feature Fred being locked in by the cat and the famous cry of 'WILMA'! The closing credits now have Pebbles and Bamm-Bamm singing their song at the Hollyrock Palace.
This episode was recorded on 4-13-65.
The VHS and TV version of this episode feature the stereo theme song, but the DVD set still has the 1963 monotone.
The character Eppy Brianstone is based on Brian Epstein, the manager of The Beatles.
