Kaijûtô no kessen: Gojira no musuko

Reporter Goro Maki (Akira Kubo) stumbles upon scientists conducting weather experiments on Sollgel Island, where he discovers a mysterious woman, Saeko (Bibari Maeda), and a helpless infant monster, Minilla, that Godzilla must adopt and raise as one of his own. As Minilla grows, Godzilla begins to teach him how to roar and use his atomic ray, and they work together to defeat giant spiders, including Kumonga, and eventually find refuge on an American submarine. Godzilla and Minilla eventually hibernate together as the island is buried in snow and ice.
