In this wonderful book about acceptance and diversity, Elmo becomes friends with a blue monster named Angela. Unlike on Sesame Street where monsters of all colors live, Angela's neighborhood only has blue monsters. The new friends soon learn that red monsters and blue monsters may look different on the outside, but they are very much alike on the inside! The subtle messages within the story will help young children to be more accepting and inclusive when it comes to people who look and/or think differently than they do.
