Walter loves his life as the resident dog aboard a ferry, where he befriends the travelers, barks at the seagulls, and helps the crew with their jobs. He does not love Cupcake, the captain’s pampered cat. One day, after Cupcake lands him in trouble, Walter disembarks onto the island. He enjoys exploring, but the people are unfriendly, and when a chilly fog rolls in, he can’t find the ferry. Walter feels miserable until Cupcake unexpectedly appears and leads him home. Children will relate to this lovable dog who always wants to help but is often turned away for reasons that don’t make sense to him. The story comes to life in Wong’s ink drawings, brightened with watercolor washes. Besides developing the settings with delicate precision, the illustrations portray Walter as a dog full of energy and personality. While appreciating the pun in the title is optional, many kids will enjoy this canine adventure story.
