Humphrey and his friends in Room 26 let their imaginations loose! Ahead of a big author visit to Longfellow Elementary School, they 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 in Room 26, and the new school pet Gigi, a guinea pig, Humphrey encounters real live parrots, dragons and even ghosts - and finally manages to let his imagination soar.
