Meet Polipo, a curious octopus. All summer long he watched the big boats come and go above him from his home under the reef. He wondered where they came from. He couldn't stop thinking about that. His decision to leave home was an easy one for him. But his Momma is not so sure about this. He finds an easy way to travel as a stow away on a cruise ship. Where will it take him? He didn't think about that past his lunchtime meal of clams and snails! Now he finds himself excited but alone. This is a very different experience. After the cruise ship stops, what adventures await Polipo?
