The holidays have come and gone and Humphrey is shocked at the surprise in Room 26-a new class pet!
Humphrey tries his best to be welcoming, but Og the frog doesn't respond to his friendly squeaks or visits. The students are so interested in Og that they almost stop paying attention to Humphrey all together.
Humphrey doesn't like the mad-bad-sad feelings he's had since Og's arrival, but luckily he still enjoys his adventures on the weekends with different kids.
Friendship can be tricky, but Humphrey is an intrepid problem-solver. If any hamster can become buddies with a frog, he can.
