When Duncan goes to use his crayons he finds notes from all the crayons and how they are feeling! Red is overwhelmed. Purple is tired of being colored outside the lines. Beige doesn't like to be called light brown or dark tan and doesn't like being in second place to Brown! Grey is tired. White is feeling empty. Black doesn't like to be an outline. Green is writing for Yellow and Orange because they won't talk, they both think they should be the color of the sun! Blue is feeling like he needs a break, Pink is feeling unused and Peach doesn't like having a cover! Duncan has to figure out how to make all the crayons happy so he can continue to color! I would use this book to work on expression and voice!
