Designed for navigation over a wide variety of terrains, the hover car was the pinnacle of light-duty surface transport in the late 1960's. The inhabitants of the deep-sea submersible Explorer used this vehicle when an underwater rockslide forced the ship to the surface just off the coast of the mysterious Mondo Island. The highly advanced hovercraft ferried the crewmembers ashore, but their ultimate encounter with the monstrous ape King Kong and the fierce dinosaur Gorosaurus prompted the members of the expedition to utilize the craft in order to bid a hasty retreat. The vehicle was almost decimated when the terrible Giant Sea Snake suddenly appeared; however, King Kong repelled the reptile long enough for the crewmembers to escape.
