Monkey Business — Elise Leonard

Al and Keith are always monkeying around, but the one thing they really don't need is an actual chimp! That's exactly what they find one day while hanging in the park. Where did it come from? What should they do with it? And why does it keep kissing Keith? Al decides they can't leave the poor animal, so they take it to Al's room, and the zoo, and the movies. When they get tipped off that an animal testing lab is missing one of its chimps, Al and Keith find themselves on an animal rights crusade that's about to get wild!
