Jonny Quest The Dreadful Doll (1964–1965) Online
As Dr. Quest continues his fish studies, Hadji and Jonny scuba dive and spot a submarine entering a cave. Before the boys can convince Race and Dr. Quest that what they saw was not an illusion, an emergency call for help arrives. The daughter of the last plantation owner on Tanaiga Island has fallen under a voodoo spell that has scared away all other owners. Korbay, a former no-account, is now the powerful witch doctor responsible. Dr. Quest feels the sudden catatonia affecting islanders is medical rather than mystical in nature, but before he can concoct a remedy, the Quest ship is invaded at night, with a suga doll left behind to intimidate the doctor. As Benton brings remedy to two put under Korbay's "spell," Race dons scuba gear to check out the boys' submarine story and is captured while discovering much more than anyone imagined.
