You have heard of ants in your pants. Well, Penelope Cole has a bigger problem. She has piggies in her pockets. They are messy and loud and never leave her alone. They get her into trouble at school, make a mess of her room, and steal her dinner. The worst part is no one else can see them and no one understands that she is really trying to keep them under control. How can she help them be good? This book is a fun way to talk to younger children about challenging behavior and impulse control. The letter at the end gives the opportunity to discuss what Penelope Cole can do to help her piggies behave.
