Kyorochan (キョロちゃん) is a Japanese cartoon bird that serves as a mascot for a brand of Morinaga chocolate known as ChocoBall. He first appeared in 1967 in the anime television series "Uchuu-shonen Soran" (Space Boy Soran). Originally, when the series began in 1965, Choco-Balls were consumed by a cartoon "space squirrel" known as "Chappy"; it was found that sales of Choco-Balls did not increase. Therefore Kyorochan was devised in 1967 as a replacement. Wario Ware, Inc.'s Pyoro was based on Kyorochan.
