The Frankenstones

They were featured as the managers of a condorstonium development called Deadrock Arms that Fred Flintstone and Barney Rubble considered moving their families into.

This version of the Frankenstones continued to appear throughout the run of the prime-time specials: Fred's Final Fling (1980), Wind-Up Wilma (1981) and Jogging Fever (1981).

The Frankenstones starred in their own eponymous segment on Saturday mornings as part of The Flintstone Comedy Show which premiered on November 22, 1980.

This version of the family consisted of: The previously soft-natured Frank is now hot-tempered and wired with his voice provided by Charles Nelson Reilly in his traditional high-pitched, hyper-whiny style.

Following the cancellation of The Flintstone Comedy Show in 1982, the Frankenstones have never been referred to in any subsequent spin-off series, specials or animated movies.
