Just days after teasing photos on social media, KAWS is collaborating with the Japanese television series Hirake! Ponkikki on his 2021 winter vinyl figures. The name of the KACHAMUKKU figure came together by combining the names of Hirake! Ponkikki characters Gachapin and Mukku. The figure split down the middle with Gachapin on the left side and Mukku on the right while KAWS put his signature motif bone shaped ears and X marked eyes.
The KAWS KACHAMUKKU Green/Red Figure released on October 9th, 2021 in Japan and retailed for $320. The figure later released on KAWSONE on April 5th, 2022.
