I have the same question! I am doing a book report on the book but I think the dust can be a possible antagonist hope this helps! :-)
i would say that the protagonist is Peter himself, and the antagonist is also Peter. This is because Peter is the main character, which makes him the protagonist, and he fights against himself when he looses the penny, which make him the antagonsit aswell.
