On December 31, 1964, Jonny Quest moved to the Thursday-evening timeslot previous occupied by another Hanna-Barbera prime time cartoon series, The Flintstones, which itself took over Jonny Quest's Friday-night berth. The occasion was marked by the episode titled "The Fraudulent Volcano," in which the Quest team was again menaced by the insidious Dr. Zin. This time, the villain has reactivated a long-dormant volcano, intending to destroy everything in his path unless his demands are met. Want to bet that the good guys disrupt the eruptions in record time? ~ Hal Erickson, Rovi
