Children who have reached the toilet-training stage will think this is the funniest book they've ever seen. Most parents will smile, too, as children and parents turn the pages and follow the antics of a comical group of animals. The color illustrations on every page are large and bold, and the story concludes with a sound button for kids to press. One running rabbit, two little pigs, three tiny birds, and an assembly of other animals are all running toward their potties. On the book's very last page, kids open a double gatefold spread and find that the animals have all reached their destinations. A sound chip embedded in the illustration gives off an appropriately flatulent noise.
