Whenever mysterious distress signals appear in the microscopic world of Green Green Grassland, the Goat Action Team immediately springs into action. Riding their magical cars with various functions, Pleasant Goat and his friends set off for the microscopic world to help insects in trouble. During their adventures in the microscopic world, the team encounters many old insect friends. Snail Express is still delivering packages; Dung Beetle Uncle and Little Dung Beetle continue pushing mud balls every day; and the bee family, led by Captain Bee, remains hard at work collecting honey. At the same time, more new friends appear in the grass, such as the loud-spoken yet sensitive Cicada Brother; the trio of crickets with distinct personalities who constantly bicker but collaborate seamlessly in music; and the warm-hearted, highly skilled Mantis Heroine. The Goat Action Team forms deep friendships with these adorable insect companions, helping them solve various difficulties while also gaining inspiration and growing through their interactions.
