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.

When summer arrives, Humphrey, the pet hamster of Longfellow School's Room 26, is surprised and pleased to learn that he will be going to Camp Happy Hollow.

It's almost Halloween, but the scariest thing in Room 26 has nothing to do with creepy decorations or spooky noises: Mrs. Brisbane is missing! This might be the biggest mystery Humphrey has ever tried to solve.

Humphrey, the pet hamster of Longfellow School's Room 26, learns that his classroom is full of secrets, the most important of which is that a student will be leaving soon.
