Percy Keeps Warm is a short rhyming magazine story.
Percy takes a racehorse called Icy Blast out into the countryside to practice his running. After a long gallop, the jockey covers his horse in blankets so that he would not catch a chill.
Then, Percy grows cold and tired and has to take the racehorse home. Seeing Percy's condition, the jockey and the trainer decide to give Percy some warm blankets of his own.
