Luther's Halloween is a fun little book I grabbed at the library for John about a boy and his triceratops, Luther. Luther dresses up as a pirate for Halloween which makes it even more perfect for John. Dinosaurs AND pirates??? Can't get much better than that!
Luther is pb&j on wheat holding a sword pick. There are also grapes, all-natural fruit snacks, a Mini Slim Jim, and a colby jack "Roar." (John is very much a creature of habit. He could probably have this same exact combination of food every day and not get tired of it!)
