Friendship According to Humphrey

Friendship According to Humphrey by Birney, Betty G.. hardcover edition. ISBN: 9780399242649.

Everyones favorite classroom pet has a lot to share - and learn - about friendship! After the holidays, Humphrey is shocked by a big surprise in Room 26-a new class pet! Humphrey tries to be welcoming, but Og the frog doesnt respond to any of his friendly squeaks or visits (remember, he has a lock-that-doesnt-lock). Plus, the students are so interested in Og, they almost stop paying attention to Humphrey altogether. Humphrey doesnt like the mad-bad-sad feelings hes had since Og came, but luckily he still gets to have adventures with different kids on the weekends. Friendship can be tricky, but Humphrey is an intrepid problem-solver. If any hamster can become buddies with a frog, he can.
