Real Koke-kun  

リアルコケくん

The franchise known as KOKE-kun features eight cartoon characters that represent different species of moss. In order to promote the brand, a campaign called Real Koke-kun was launched, which involved flash mobs dressed in the likeness of the main green moss character appearing throughout Japan. Additionally, an animated version of Real Koke-kun was created by Takashi Taniguchi during this time.
