Dr. Daino, a globe-trotting archaeologist, traverses ancient ruins alongside his son, Taiga. During a South American expedition, they cross paths with ruthless treasure hunters and unearth Oobats—a dormant 50-meter stone bird statue. The colossal artifact awakens with startling sentience and escapes the site. Investigations uncover Oobats’ apocalyptic purpose: paired with the "Ooparts Egg" relic, it gains the power to annihilate universes. Partnering with Taiga, Dr. Daino races to intercept the rogue statue before it claims the Egg, striving to dismantle its world-ending capabilities.
