Panda! Go Panda! (1973)

Cheerful Mimiko has a wonderfully strange family—a Panda for her Papa; and his son Panny, calls her Mom! When Panny follows Mimiko to school, he must pretend to be a teddy bear so Mimiko won't get into trouble. Despite his efforts to behave, Panny causes trouble in school and now the school is after Panny! Then, Panny makes a new friend, Tiny, a baby tiger who's wandered off from the circus.
