在幼儿园的霸王龙小队（四个快活、有趣的孩子）不断地发起各种善意的小作乱，让教师和家长们不得不笑而歪头，但是他们却有一个守护者——厉害大师吴爷爷（林永健 配音）。虽然吴爷爷外表阴冷幽深，但其实深情温柔，在他面前，小龙团队只得乖巧地侍奉着他。
由于吴爷爷的教育和感化，小龙团队 gradually realized that only by bringing joy and happiness to others through their mischief, can they truly succeed in it. Thanks to Wu's introduction, the little dragons found themselves in a nursing home, where they used their fists and feet to bring laughter and joy to the residents, turning the place into an ocean of happiness.
