This movie, another from the older production from Toei Animetion for children, follows the adventures from a little panda that leaves his current family and wants to travel.

Pankun is a baby panda who was abandoned in a forest where pandas live. His favorite possession is an old mitten that was in the box with him when he was abandoned. Pankun loves bread, and his tummy rumbles whenever he sees the two pieces of bread, Shokupan and Koppepan.

The anime shorts are set in the fictional Line Corporation with a motley crew of idiosyncratic workers. There is the narcissistic section head and president's son James, the subsection head Moon (who is always gone somewhere but somehow gets his work done), the quiet but kindhearted subsection head Brown, and the subordinate Connie who is in an endless loop of yo-yo diets and weight gains.

The movie starts out with Katsuhiko going to the US, with Kasumi and Yusaku seeing him off at Narita. Two years later, Katsuhiko is a professional racer, and comes back to Japan to race (and to marry Kasumi). Yusaku's hobby is photography.
