You can learn a lot about life by observing another species. That's what Humphrey was told when he was bought as a classroom pet for Room 26. And it's definitely true! In addition to his classroom escapades, each weekend he gets to sleep over with a different student like Stop-Giggling-Gail and Repeat-That-Please-Richie.
