Tang Tang found five cool toys in the box in the new attic. They can walk and talk. It's like magic. They are inseparable from Tang and Tang. They hide in their schoolbags and accompany Tang and Tang to any place. Each little toy has its own unique personality. They can always find the most imaginative, adventurous and interesting way to help Tang Tang solve various problems. Whenever they encounter problems, the little toys will use their brains to analyze and judge the problems, use their rich knowledge to infer and design solutions, and finally help Tang Tang Tang solve the problems after several hands-on verification. Of course, more important than solving problems, they feel the joy of brain, hands and creativity in the process of cooperation.
