Obi by Michael Delaney

For fans of The World According to Humphrey, Obi’s newest escapade is taking her into uncharted territory— the classroom!Obi the gerbil just has to know if she is Rachel’s favorite pet. She’ll do anything to find out—even if that means going to school as a stowaway in Rachel’s backpack. She quickly finds that there’s a lot to learn as she is thrust into a world filled with stampeding children, a secret society of class pets, and a whoopee cushion. Worst of all, Obi becomes trapped in the school overnight! With the same wits, determination, and bravery that make her first two books so appealing, Obi the Jedi gerbil’s humorous adventures continue, peppered with the same comical cartoon illustrations that make each page a delight.
