A U's Magic Radish mainly tells the wonderful life of A You and a greedy fat boy, a rigid and dogmatic man and woman, Amy who likes lovely things and her pet dog Xiaobai on a magical island-Radish Island. They made a promise to the doctor of agriculture to protect the safe growth of this radish, and their opponents were three rabbits with different ideals-rabbit flying, jumping rabbit eager to travel around the world and swinging rabbit eager to eat delicious radish. They are not bad people, they just want radishes to realize their dreams.
