This is the first episode to feature Pebbles in the opening credits, showing her playing with the sponsored product, "Kenner Flintstone Building Boulders", which were Lego-like Styrofoam bricks that interlocked. In syndication, the box seen in the Pebbles shot only says "Building Boulders."
Ann-Margret sung to Pebbles "The Littlest Lamb" after Pebbles was crying.
Ann-Margret is listed in the end credits among voices as guest star.
This is the only time the Flintstones' car is shown with headlights.
