7365 Terror Off Tahiti,

Mattel’s Big Jim Terror Off Tahiti, reference 7365, is a vintage Adventure Series set documented between 1973 and 1974, with 1974 appearing on several European collector references. Designed around an underwater treasure-hunting scenario, the set equips Big Jim for a hazardous deep-sea expedition. Confirmed contents include the yellow deep-sea diver outfit, diving helmet, twin air tanks with harness, boots, a treasure chest with gold-colored coins, and the distinctive giant clam. The clam incorporates a spring-like closing action, creating the “terror” featured in the illustrated adventure. The original packaging explicitly promotes the “Giant Clam and Lost Treasure” theme. This unusual Mattel reference combines costume, diving equipment and interactive scenery in a particularly elaborate early Big Jim collection set.
