Duel in the Devil's Cauldron

After Covergirl and Timber save the lives of the G.I. Joe team, the Joes continue to search for a way to stop the Cobra terrorist organization. Both forces begin missions to retrieve the third element, a meteorite buried in a volcano. The Joes try to lift the meteorite, but are thwarted by Cobra, led by Destro, who causes the volcano to erupt, ejecting the meteor. But both forces obtain the third element. The Joes have all three elements and want to attack Cobra, but Duke has no recollection of where Cobra Mountain is located.

"Now you know. And knowing is half the battle." The Sunbow run closed every episode with a public-service spot delivered by a Joe character, addressing kids on a real-world hazard or virtue. The cartoon's deeper ethic, threaded into the writing across the run, was that Cobra's worldview was based on fear and the Joes' was based on responsibility.
