Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack
A group of teenage campers disturbed Mothra's shrine after robbing a convenience store near the Lake Ikeda. Mothra awakened and pulled the teenagers underwater, wrapping their bodies in a cocoon of silk. Mothra then encased herself in a cocoon which sat on the lake's surface. Groups of people began to congregate around the lake, observing and sometimes praying to the strange cocoon. Eventually, as Godzilla approached Yokohama, the cocoon split open and Mothra emerged in her imago form before flying off to confront Godzilla.
