The Spinach in my Teeth begins when a little boy named Riley is getting ready for his first day at a new school. Riley's mom packs his favorite lunch, a big spinach salad. Of course, it gets stuck in his teeth. After the embarrassing discovery that he had been walking around sporting a green glob all afternoon, an encounter with a sly, sassy, rhyming rabbit and her friends-who naturally love spinach-gives Riley a new appreciation for the leafy green. And he passes it on to his friends, too!
