Niannian has a very bad habit of not taking care of things. Toys usually don't survive two months with him. Fortunately, the toy car that was thrown away by Niannian started a fantasy journey with Dudu in Diudiu Kingdom. During this period, they rescued a rag doll that was accidentally thrown away, and also made a good friend, and this good friend was Chen Chengzi, their classmate every year. Classmate Chen Chengzi successfully integrated into the Diudiu Kingdom with the help of the Wildcat Family. After Niannian accidentally throws away the pearl necklace that his grandfather left for his grandmother during his lifetime, Chen Chengzi, Dudu, and a group of good friends from the Diudiu Kingdom come to accompany Niannian to search for the pearl necklace. At the same time, they also met Grandma Tao Xin, who was very skilled in medicine. After they finally recovered the pearl necklace from the migratory birds, bad news came. The Diudiu King, who was hidden deep underground and had never been known to anyone, might be destroyed. The construction of the city required rectification of the area of the Diudiu Kingdom, which meant that all the lost items in the Diudiu Kingdom were once again at risk of becoming homeless. At this time, Niannian has become more caring about things with the help of Dudu and Chen Chengzi, and he vows to help his good friends no matter what. Saving and being saved begin at the same time.
Intention: To save is to be saved at the same time
