To make matters worse, the students are so fascinated by Og, they almost stop paying attention to Humphrey altogether! Humphrey knows that friendship can be a tricky business, but if any hamster can become buddies with a frog, Humphrey can! “[Humphrey’s] lively, first-person narrative, filled with witty commentary on human and hamster behavior, makes for an engaging, entertaining read.” – Booklist “ Wise observations (a la Beverly Cleary) of friendship in the story of two newcomers, a frog and a shy little girl.” – Chicago Tribune
