Koupen-chan (コウペンちゃん) dressed as a pumpkin for Halloween. Rurutea's emperor penguin chick became a phenomenon by praising people for the smallest things — getting out of bed, showing up, trying at all — and the Chinese fandom nicknamed it 正能量企鹅, the positive-energy penguin, for exactly that reason.

A soft plush mascot charm for a bag, backpack, keyring or pencil case, and a gentle desk companion the rest of the year.

A seasonal Japan-exclusive release in very limited quantity. Also available in the matching black cat costume.
