Vacationing American pilot Frank Harper was present when a volcano exploded on the island of Napuka. From inside the fury of the volcano came a smoking fiery biped, a humanoid mass of lava! It seemed that the lava was actually a cover for whatever creature was inside but this was destined never to be revealed.
Luring the apparently mindless entity to a nearby airbase, Frank Harper managed to lead the creature into a wind tunnel. Once activated the air blasts of the wind tunnel frightened the monster off and it went back down into the heart of the volcano.
