Book excerpt: Humphrey's eleventh adventure celebrates stories, writing, and the power of the imagination! Imaginations are running wild in Mrs. Brisbane’s class, but Humphrey is stumped. His friends are writing about where they would go if they could fly, but Humphrey is HAPPY-HAPPY-HAPPY right where he is in Room 26. It’s pawsitively easy for Humphrey to picture exciting adventures with dragons and knights in the story Mrs. Brisbane is reading aloud. He has no trouble coming up with Plans to help his friends and tricks to entertain them. His imagination even goes a little too far when he wonders if Carlos’s imaginary friend might be a ghost. If only his imagination wouldn’t disappear when he tries to write. Luckily, Humphrey likes a challenge, and Mrs. Brisbane has lots of writing tips that do the trick.
