Daikyojū Gappa

An expedition from Tokyo heads to Obelisk Island, which a greedy entrepreneur (Mr. Funazu, the President of Playmate Magazine) wants to turn into an island resort. The natives of Obelisk welcome the expedition, but when two members, Hiroshi and Itoko, venture into the forbidden part of the land, they skeptically venture ahead, despite the pleas of a native boy named Saki. They enter a cavern (which was blocked by a statue that had collapsed) and find a giant egg, out of which hatches a baby monster, a "bird-lizard", referred to as a "Gappa" by the natives, who plea with the scientists not to take the baby away, lest they anger the baby's parents, to which the scientists react with skepticism. Sure enough, they take the baby away, and soon, inside the caverns, its two larger parents rise from the underground waters! They rise from beneath the island volcano, destroying everything in their path, with Saki being the only survivor left on the island (rescued by an American navy fleet and brought back to Japan).

Meanwhile, back in Japan, the baby "bird-lizard" monster makes world headlines, not to mention getting being experimented on by scientists. But to the shock of the expedition members, they hear news of two giant flying creatures appearing over Sagami Bay. The Gappa parents ravage cities looking for their offspring, and are impervious to military weapons. Hiroshi, Itoko and Professor Tonooka (a scientist from the expedition) have figured that the "Gappas" aren't a legend after all. They, and Saki, try to plead to the headstrong Mr. Funazu to let go of the baby and return it to its parents. Will they convince him before the Gappas destroy Japan and perhaps the world?
