The first book in the series about everyone's favorite classroom pet!You can learn a lot about life by observing another species. That s what Humphrey was told when he was first brought to Room 26. And boy, is it true! In addition to having FUN-FUN-FUN in class, each weekend this amazing hamster gets to sleep over with a different student, like Lower-Your-Voice-A.J. and Speak-Up-Sayeh. Soon Humphrey learns to read, write, and even shoot rubber bands (only in self-defense, of course). With lots of friends to help, adventures to enjoy, and a cage with a lock-that-doesn t-lock, Humphrey's life is almost perfect. If only the teacher, Mrs. Brisbane, wasn t out to get him!Boys and girls can't help falling in love with Humphrey!"
