A short film only screened at the Ghibli Museum in Mitaka.

The puppy Koro rushes out of the house chasing Sawako leaving for school, but Koro gets lost. In unfamiliar places, Koro is nearly run over by a car, threatened by an alley cat... For little Koro, everything he encounters outside is new and a big adventure. Meanwhile, Sawako comes home to learn that Koro is gone. She frantically tries to find him.
