Friendship According to Humphrey by Betty G Birney
Faber and Faber ISBN 9780571233243
Dear Friends, When Og the Frog came to live in Room 26, I felt a little jealous. Still, I tried to be welcoming but I soon discovered that it's HARD-HARD-HARD to make friends with a lumpy, bumpy frog! Then I found out that my fellow students were having problems with their friends, too. A.J. and Garth had to deal with a bully named Mean Martin Bean. Heidi and Gail had a terrible argument, and Miranda-Golden had a new stepsister who wasn't nice at all. Then there was the Poetry Festival, the magic show and the snowstorm! How could one small hamster solve all those problems? Luckily, I wrote the whole story in my notebook so you could share in my adventures.
