Everything is Mine

My name is Marcello Von Cauliflower Boneaparte Jackson and everything is mine. Marcello is kind, clever and very loyal. Unfortunately, there is one problem. He believes that absolutely everything is his. A slipper? It's his. Pork chops from his owner, Leo's dinner plate? It is absolutely his. An entire park? Oh that's his, too. Marcello (and his list of things that he owns) is out of control! Will Leo be able to remind him what is really important?
