Happy is an adventurous little crab whose world is suddenly turned upside down (literally!) when a mama and her son discover his large, unbroken shell while on vacation at the beach. After deciding to keep the shell as a souvenir, the boy unexpectedly feels the crab move inside and is suddenly faced with a decision: take him home or let him go. His compassion for the crab and thoughtful decision to release him gently reminds readers of the importance of selflessness and highlights how our environment, relationships, and experiences contribute greatly to our happiness.
