开心宝贝之开心联盟争霸战

Two special guests arrive at Star Planet: Ambassador Wangcaixing and Ambassador Miaomeixing. It is said that the two ambassadors were sent to Star Planet to establish diplomatic relations. However, Wangcaixing and Miaomeixing are two hostile planets, and they constantly quarrel with each other. The purpose of their visit to Star Planet is, on one hand, to establish diplomatic ties, and on the other hand, to make things difficult for each other. Meanwhile, the ambassadors' children—Lele and Keke—attend Superstar Academy. The constant quarrels between the two children force the superheroes to not only save Star Planet but also prevent the disasters caused by their arguments. At the end of this season, Garlo, a character introduced from the third season, sacrifices himself to protect Star Planet.
