A new school year and new friends for everyone's favorite classroom pet! Humphrey is excited to get back to Room 26 and see all his old classmates. But on the first day of school, a bunch of strange kids arrive and no matter how loudly he squeaks up, they don't realize they're in the wrong room! Finally Humphrey realizes that these kids are his new classmates, and he sets off to learn all about them.

Humphrey is unsqueakably excited—a special guest is coming to Room 26! But when he sees who it is, he’s SHOCKED-SHOCKED-SHOCKED. The guest is a big dog! And Mrs. Brisbane doesn’t seem worried at all! Luckily, this dog is very gentle. His name is Happy, and he’s come to help Humphrey’s classmates with their reading. Then they hear about more dogs—a friendly one who can do tricks and sing, and a beloved pet who has gone missing. Of course everyone wants to help find her.

The sixth book in the beloved and award-winning school hamster series! When Humphrey hears that school is ending, he can't believe his ears. What's a classroom hamster to do if there's no more school? It turns out that Mrs. Brisbane has planned something thrilling for Humphrey and Og the frog: They're going to Camp Happy Hollow with Ms. Mac and lots of the kids from Room 26! Camp is full of fun-fun-fun new experiences, but it's also a little scary. There are fur-raising wild sounds and smells, and there's something called the Howler to watch out for.

Humphrey has always investigated things, like why Speak-Up-Sayeh was so quiet and Tall-Paul and Small-Paul didn't get along, but this is a true mystery - Mrs. Brisbane is missing! She just didn't show up in Room 26 one morning and no one told Humphrey why. The class has a substitute teacher, called Mr. E., but he's no Mrs. Brisbane.
