Peep! Peep! Moo! Moo! is a magazine story.
Edward likes passing the farm where he sees cows, pigs, and a donkey. One evening, Edward tells the other engines about the noises the farm animals make. James is sure Edward is mistaking the noises that the animals make. Percy is sure that Edward is right and concludes that James must be puffing past the farm so fast that all the noises get muddled together. The next day, James agrees to go past the farm slowly and he listens carefully. That night, James has to admit to everyone that he was wrongs.
