The only one I really remember was the Berenstein Bear's Messy Room. They were punished because their room was messy, and the book chronicles how they clean it up, how it's organized, etc. It's so cute. The pictures were so detailed and colorful. To me, a children's book wouldn't be a children's book unless it had some kind of fantasy or imagination.
Kids have such a fascinating perspective on life, and their imagination can absolutely run wild.
I think many children's books play on that, and exaggerate it to a degree to keep the child's interest. I like Haroun because it takes that fantasy aspect and runs wild with it. One thing that I thought was so funny were the names Rushdie chose for his characters.
