After a long winter vacation, Humphrey the hamster can’t wait to see his friends in Room 26 again. But on the first day back he gets a big surprise: Room 26 has a new class pet, Og the frog! Humphrey can’t wait to be friends with Og, but Og doesn’t seem interested. To make matters worse, the students are so interested in Og, they almost stop paying attention to Humphrey altogether. Luckily he still gets to go home with different kids on the weekends and help them out with their problems. Humphrey knows that friendship can be a tricky business, but if any hamster can become buddies with a frog, Humphrey can!
