Imagination According to Humphrey by Betty G. Birney

Ahead of a big author visit, Humphrey and his friends try writing their own stories, but Humphrey worries that hamsters don't have any imagination; he's finding creative writing just too hard. While he helps out his friends, and the new school guinea pig, Gigi, Humphrey encounters real, live parrots, dragons and even ghosts . . . and finally manages to let his imagination soar.
