The first 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! There are always adventures in the classroom and each weekend he gets to sleep over with different students. Humphrey learns to read, write, shoot rubber bands (only in self-defense, of course), turn off TVs, teach English as a second language, and more. With a lock-that-doesn't-lock and an adventurous spirit, what more could a mischievous hamster want?With a fresh voice and an engaging, hamster's-eye view of school, families, and treats to hide in a cheek pouch, Betty G. Birney's Humphrey will elicit laughter and demands for hamsters in every elementary classroom.

Also available in Spanish as El Mundo de acuerdo a Humphrey.
