Escape!! The Underwater Volcano Erupts

A powerful local earthquake of magnitude seven strikes in Australia, thanks to explosives the Destrons have set off in their construction of an undersea base. Under orders from Ginrai, Lightfoot descends to the sea floor in robot mode to investigate. As he checks over an undersea volcano, he comes under attack by hundreds of Seacons, leaving him pinned under a large slab of rock. Ginrai and the Headmaster Jrs then travel there to rescue him. Super Ginrai goes by himself to rescue Lightfoot, where he is ambushed by King Poseidon, who causes an avalanche on top of them. Meanwhile, the Headmaster Jrs. are working to evacuate the people from the ruined cities. Godbomber goes into the ocean to help rescue Super Ginrai, who is trying to break out from under the ocean floor. Ironically, the Destron undersea base is buried under an avalanche of flaming rocks from volcanoes. While Lightfoot deals with the other Seacon gumbies, God Ginrai battles King Poseidon above a river of lava.
