Synopsis:
Short film shown only in the Ghibli Museum in Mitaka. The nine-minute short adapts a picture book by Rieko Nakagawa and Yuriko Yamawaki, the author and illustrator of two previous books that inspired Ghibli shorts (Sora Iro no Tane, The Whale Hunt). In the story, a boy named Yuuji and a rabbit named Gikku find a stick at the same time, and decide to compete in games to decide who can keep the stick. However, whether it is a foot race, long jump, or sumo wrestling, they always end up in a tie.
