The Hatrocks are very sad and crying because they think the last of the Flintstones, who they have been in a feud with for the last several hundred years, has died, but soon discover that one Flintstone family is still living. That family of course includes Fred. They send bait to get the Flintstones to come up and visit. Once they do the feud continues until Fred saves Pebbles and the Hatrocks’ little boy from harm. But soon after, Fred puts his foot in his mouth and the feud resumes.
