Several major changes were wrought upon The Flintstones as the animated series entered its third season. To begin with, the series was telecast in color for the first time with the episode titled "Invisible Barney" on September 28, 1962. Also, the opening credits sequence was refilmed, replacing the original action of Fred driving home, stopping at the dry-cleaners, picking up a newspaper and crashing into his garage with the more familiar sequence of Fred knocking off from work, then taking Wilma to a drive-in movie. Additionally, the series' longtime instrumental theme music "Rise 'N' Shine" was supplanted by the now-legendary vocal composition "Meet the Flintstones" (and for the benefit of those who still can’t understand the middle lyrics, they are "Let's ride with the family down the street/through the courtesy of Fred's two feet"). Finally, and most importantly, stone-age suburbanites Fred and Wilma Flintstone became parents. The blessed event occurred on February 22, 1963, in the episode titled "Dress Rehearsal"; on that occasion, Wilma gave birth to a baby daughter named Pebbles. (Trivia note: a least two of the pre-Pebbles episodes, which alluded to the fact that Fred and Wilma were childless, had new footage added for their original network reruns so that they would appear to be "flashbacks". These additional scenes were shown but once, and have never been syndicated). Unlike previous seasons, The Flintstones' musical highlights were few and far between during Season Three. An exception to this "The Twitch" (from the episode of the same name), a spirited takeoff of the then-current dance craze "The Twist." Although the novelty of The Flintstones had worn off a bit during its three years on the air, the series still posted excellent prime-time ratings, finishing the season as America's 30th most popular TV program, just one notch below the live-action western Have Gun--Will Travel. ~ Hal Erickson, Rovi
