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...

Dear friends, I Love-Love-Love being the classroom hamster in Room 26, Longfellow School. I've learned a lot about reading, writing, maths and making friends... and I've had amazing adventures in and out of my cage, too. But I also love solving puzzles and riddles in the tiny notebook I keep hidden in my cage.

Dear Friends, I may be a small classroom hamster, but even I'm amazed at how many unsqueakably exciting adventures I've had. I've had a spooky mystery to solve on Halloween, nighttime escapades at school and even gone to Winter Wonderland. I've had so many HO-HO-HO hilarious adventures.

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.

Dear Friends, At last, spring has come! Lucky for Room 26 where I'm class hamster because they've got a Family Fun Night planned at Longfellow School. It'll be great to get to know my classmates' families. I might even start thinking about what family means to me - especially as families come in all sorts of shapes and sizes. Humphrey.

A J and Garth had to deal with a bully named Mean Martin Bean. Heidi and Gail had a terrible argument, and Miranda-Golden had a new stepsister who wasn't nice at all. Then there was the Poetry Festival, the magic show and the snowstorm! How could one small hamster solve all those problems?

When all sorts of problems crop up in the classroom, from Pay-Attention-Art's marks going down, to Golden-Miranda finding herself in big trouble, Humphrey must step in to lend a helping paw. Using his charm, resourcefulness and wisdom, he's certain to have a plan.

When Humphrey hears about a sailing competition on Potter's Pond, he longs for a BIG-BIG-BIGGER adventure. And believe us, he gets one... but it isn't all smooth sailing. He helps out his classmates, takes an unsqueakably dangerous voyage of his own, and even comes face-to-face with a pirate.

When Humphrey learns that school is ending, he was unsqueakably worried. What would he do once he lost his job as classroom pet? It turns out that summer is wilder than Humphrey thought school could ever be. He sees new sights, makes new friends, and has FUN-FUN-FUN! But he also has to deal with new creatures...

Humphrey enjoys surprises as much as the next hamster, like his brand new hamster ball or a surprise part, but sometimes surprises can be bad... Like coming whisker to whisker with a cat (EEK!) or having an alien from another planet move into Room 26.
