Bath-time turns into a fantastical adventure in the hands of two of the world's most-loved picture book creators. The story begins with Sammy, whose obnoxious neighbours get to go to the beach in their brand-new boat while he has to get clean for a visit from grandma. Worse, it's a bath in the strange tub his dad just bought at a garage sale! But the magic of the tub soon has Sammy roaring out to sea, befriending a giant sea serpent, conquering pirates in a huge soapy battle and returning home with the greatest of treasures. Bath-time will never be the same! (Plus Grandma's got a few surprises of her own!)
