The Green Grassland is about to transform into a high-tech city. On a bright, sunny day, the little friends, including Pleasant Goat (voiced by Zu Qing), Pretty Goat (voiced by Deng Yuting), and Lazy Goat (voiced by Liang Ying), decide to dig a hole and bury a time capsule as a memento. Even their sworn enemy, Wolffy (voiced by Zhang Lin), eagerly joins in on this meaningful occasion. Suddenly, a tremendous explosion shatters the peaceful atmosphere, and a huge crater appears in the middle of the grassland. At its center lies a black, cross-shaped stone. This small mishap does little to disrupt the friends' plans. As dusk falls, they gather in the square for a group photo and to wait for the fireworks display. While chasing and roughhousing with Wolffy, Pleasant Goat and the others stumble upon Dr. Ti, a mysterious man covered in machinery and carrying that strange stone. This encounter takes the friends to the Green Grassland fifteen years in the future, where a brand-new adventure awaits...
