Four years after the original Kabi Usagi shorts, a new episode was released. This was longer than the original, contained smoother animation, was fully voiced (unlike the original which has no voice acting), and numbered as "story 01." A series/additional numbered shorts were expected under this franchise revival but it never came to fruition after this first episode.

Shorts focusing on the cute (albeit bittersweet) lives of several rabbits with mold growing on them. They dream to spread their mold all over the world.
