"Volcano Island" is the 16th episode of Inspector Gadget.
It is a beautiful day in the South Pacific and, while Penny and Brain play volleyball on the beach of a tropical island resort, Gadget is surfing just offshore. A call from the Top-Secret-Gadget-Phone hastens his return to dry land (and away from the jaws of Claw's mechanical shark) where he learns he must protect this two-island tropical paradise from Claw's top man, who is the M.A.D. Prophet this time, a presumably eccentric old kook with wild eyes who loudly preaches doom for the islands and their inhabitants.
Gadget soon becomes a believer (and fan) of the prophet after a trip to his shack, where two of his prognostications (in the form of booby traps meant to harm the inspector) immediately come true. Penny quickly sees through the phony soothsayer's act and realizes he's working for Claw, but before she can do anything about it, she is captured and lowered in the very volcano Claw intends to trigger to erupt with explosives. While Gadget helps with a supposed sacrificial ceremony by loading this volcano with pineapples (that unbeknownst to him contain explosives), Brain rescues Penny. They're barely down the volcano's side to safety before it blows its top. Gadget, at the mouth of the crater when it erupts, fares a bit worse, but he quickly recovers and is intent on finding the prophet solely to congratulate him on another accurate prediction. The clumsy police inspector crashes into the prophet and another M.A.D. agent, and effectively captures both of them while disarming a huge bomb meant to take out the larger island.
