"New Careless and Grumpy" is another domestically produced and best-selling new cartoon program created by Shanghai Animation Film Studio with a massive investment of tens of millions, following "Big Ear Tutu." While maintaining the original style of Big Ear Tutu, it incorporates new technical elements and humorous content. The storyline makes both children and adults burst into laughter while also serving to inspire and educate children. One child is called Careless, who always forgets things and is disorganized. Another child is called Grumpy, who is particularly stubborn—when others say east, he insists on going west, always uttering the same phrase: "Grumpy!" Even worse, they are indifferent to their own flaws, especially when they fantasize about becoming adults, leading to even more jokes and bigger troubles...
