Chinese toymaker Pop Mart’s new blind box series, inspired by the Buddhist ritual instrument called muyu , or “wooden fish,” has become the latest sensation in China following the success of Labubu.

The series, titled Pucky Knock Knock, was launched in January and is priced at 99 yuan (US$14) per piece.

This plush toy keychain series showcases a charming and fluffy character that holds a wooden drumstick.

One can pull out the drumstick to knock on the toy’s head, producing the electronic sound of a muyu.

Muyu is a fish-shaped woodblock traditionally used by Buddhist monks as an instrument to maintain rhythm while chanting sutras.
