Summer is officially over, and Poppy the pirate dog is feeling very lonely. Her kids, Suzy and Tim, have gone back to school, and Mom and Dad are busy working all day. Being a pirate dog is no fun at all when there is nobody around to help you dig up the backyard and bury your treasure. To cheer her up, Poppy's family decides to bring home a brand-new friend to keep her company. Poppy is absolutely thrilled! She cannot wait to meet her big, brave new shipmate. But when the new arrival finally walks through the door, Poppy is shocked. Her new crew member is a tiny, fluffy kitten named George! George is definitely not the fierce pirate partner Poppy wanted. He tries to steal her treasure and takes the best sleeping spot right by the warm fire. What is a pirate dog to do when her new shipmate is driving her crazy?
