The fourth book in the beloved and award-winning school hamster
series!
A classroom hamster has to be ready for anything, but suddenly there are
LOTS-LOTS-LOTS of big surprises in Humphrey's world. Some are exciting,
like a new hamster ball. But some are scary, like a run-in with a cat
and a new janitor who might be from another planet. But even with all
that's going on, Humphrey finds time to help his classmates with their
problems. But will Mrs. Brisbane's unsqueakable surprise be too much for
Humphrey to handle?
Look for all twelve of Humphrey's adventures!
