Otter visits Franklin. However, her interests have changed and the changes in the village are not to her liking.; For show and tell, the class has to show their personal collection they have made, but Franklin doesn't have any and has to spend the weekend trying to find one. He finally takes an interest in rocks, which doesn't seem to interest any of the kids at first, until Mr. Owl talks about each of their histories. (thetvdb.com)
