Imaginary characters feature a multi-colored zebra grandfather, GrandZeb, and his grandson, Benzahn, who interact with human characteristics and emotions. Benzahn and GrandZeb share a special day with questions, conversation, and an adventure to the park in pajamas. Offered the opportunity to plan the day together, Benzahn makes the unusual choice to stay in his pajamas for the day. He has the support from his grandfather and the self-confidence to make the day happen as he envisioned. At the park Benzahn demonstrates his thoughtfulness to explain his ideas to his friends and enjoys a wonderful day playing with them. The story highlights the opportunities in everyday experiences to learn about each other and ourselves. Pajama Park Day explores the joy of play, creativity, and the value of inter-generational bonds. The importance of knowing oneself is highlighted as a way to navigate life's challenges. The bold and colorful illustrations by the author are paper collage designs. His grandsons, aged 5 and 8, contributed artwork using watercolor paint, pastels, and pencils. Project activities for the target audience to extend engagement with the story beyond reading include coloring pages, illustration suggestions, and related story ideas to write or dictate.
