Storyline Percy is a pig who really hates being dirty. He likes to keep as clean as possible. But his brothers and sisters think he should love getting filthy as much as they do. So they try anything they can to make him more like them. Keeping himself out of their way, and out of the mud, leads Percy into all kinds of exciting adventures. More than a story Being different is something a lot of children experience. At school for instance, where standing out from the rest can often result in ridicule and abuse. This very funny, and wonderfully illustrated story of an unusually clean pig helps provide a clear understanding of such a situation. Helping both bullied and bully come together with mutual understanding and respect.
