The stem originated from the small toy package of Poké mon shoes released by KFC on Children's Day, including Pikachu teapot/music box and Kota Duck music box.
As soon as this set meal came out, most people liked Koda Duck Music Box very much. Who would refuse to accept a lovely Koda duck? Some adults are willing to eat the children's set meal in order to get this Koda duck doll.
The duck's repeatedly swinging arm, coupled with magical music, made a group of netizens call "top". What's more, some netizens quickly remould themselves, such as pasting their handwritten words on Koda Duck's hands, or remoulding them into the images of other cartoon characters, and the dramatic effect is doubled. But some netizens said: This thing is too naive for children.
