The Flintstones' New Neighbors

The Flintstones' New Neighbors is a 1980 animated television special and the first of The Flintstone Special limited-run prime time revival of The Flintstones produced by Hanna-Barbera Productions. The special premiered on NBC on September 26, 1980.
The Flintstones' New Neighbors was animated at Filman, an animation studio in Madrid, Spain who did a lot of animation work for Hanna-Barbera between the early 1970s through the mid-1980s. This would explain why, artistically, the backgrounds in this special look very much like pencil and charcoal drawings, very different from the original series and its spin-offs.
Like many animated series created by Hanna-Barbera in the 1970s, the show contained a laugh track created by the studio, one of the last productions to do so.
