The producers of the new horror epic "Son of Rockzilla" decide to hire someone to promote the film during its Bedrock premiere. The someone chosen is Fred, who dutifully dons a "Finkasaurus" outfit and wanders around town. The sight of Fred as a monster is terrifying to some, ridiculous to others--but the most profound impact is made upon a genuine Finkasaurus. This is the first Flintstones episode to feature the voice of Gerry Johnson, who would soon take over the role of Betty Rubble full time from actress Bea Benaderet.
