The Mystery Crate / It's a Bird, It's a Plane...It's an Elephant?

A.) Aunt Nanner sends PB&J a gigantic package, but they have to wait until she gets there to open it. Ultimately, though, the kids' curiousity gets the better of them, and they realize that it would've been a lot less trouble just to wait. B.) A hot-air balloon, piloted by expert navigator Merriwether von Weasel, accidentally manages to get stuck in a tree near Lake Hoohaw. Unaware that it's just a balloon, the kids begin to think that it's actually some kind of...flying elephant?
