After witnessing a tragic accident in which a doe is killed, the boys in the Clubhouse Mysteries gang are able to rescue her orphaned fawn. But they realize that nearby construction means the destruction of the local animals' homes, so Ziggy, Rashawn, Jerome, and Rico decide to take up the cause and host a backyard animal show to raise money for the local wildlife rescue center. Dino, the adorable rescued fawn, will be the star attraction. And given that the boys have already tackled caring for a deer, managing their friends' dogs, cats, and hamsters should be easy....right?
