Crystal encountered a polar bear mother and her cub on the ice. To her surprise, the polar bear could speak! The mother said: "Our home is melting. Food is harder to find. Can you help us?" Crystal looked at the thin cub with heartache and nodded firmly. Frost said: "I know a place with plenty of food and safe shelter!"
Frost led everyone to a hidden ice cave. Inside, blue light shimmered like entering another world. Ancient patterns on the walls told the Arctic's history. Dr. Chen studied them: "These patterns record the Arctic ecosystem's secrets—precious heritage from ancient Arctic inhabitants." Crystal photographed these precious discoveries.
