This story teaches preschoolers primary-color recognition in a gentle way by using colorful balloons. The story is about a neighborhood clown named Bongo. He goes to the park every Saturday to give balloons to the local children. One Saturday, he finds himself with only one balloon left. It's the end of the day, and he is tired and ready to go home. What happens then shows Bongo that even if there is only one balloon left, you never let it go.
