Synopsis by Hal Erickson
In typical intramural Hanna-Barbera fashion, this Flinstones episode is a reworking of an earlier cartoon starring Yogi Bear. A flying saucer lands in Bedrock in preparation of a full-scale invasion of earth. To infiltrate the planet, the aliens create ten replicas of a "typical" earthman--namely, Fred Flintstone. These ten troublesome androids wander around the town shouting "Yabba dabba doo" and wreaking all sorts of comic havoc--for which, of course, the real Fred must bear the brunt of the blame!
