The third book in the beloved and award-winning school hamster series!
Humphrey loves to solve problems for his classmates in Room 26, but he never meant to create one! Golden-Miranda, one of his favorite students, gets blamed when Humphrey is caught outside of his cage while she’s in charge. Since no one knows about his lock-that-doesn’t-lock, he can’t exactly squeak up to defend her. Humphrey really has his paws full...

While continuing to help his classmates solve their problems, Humphrey, pet hamster of Longfellow School's Room 26, faces many surprises, like rolling in a hamster ball, a substitute janitor who might be an alien, and the possibility of Mrs. Brisbane retiring.

"Og the Frog tells the story of how he first came to Room 26, where he meets Humphrey the hamster, befriends the students, and writes poems and songs"--
