The Adventures of Mr. E — Michael D. Young

The desk of a third-grader is a great place to live! Just ask Mr. E, the eraser. He has been with Eli, his kid, for longer than any of the other school supplies, and he wouldn't have it any other way. But there's a new kid in town, a bully named Josh, whose desk is home to the Shapeshifter, a piece of notebook paper that can folder itself into a hundred different shapes. Josh and the Shapeshifter have a super secret plan to steal Eli's bake sale money, and Mr. E and his friends are the only ones who can stand in his way. But what can a simple eraser do against a hoarde of zombie supplies and their evil oragami overlord?
