Billy and Haley. Twin brother and sister, embark on worldwide adventures to learn more about endangered species and what we can do to help. During the week, they are just ordinary children, they go to school, they have homework, they live with their parents, and they do their chores, but on the weekends they travel the globe and are met by specialists in each location. These guides share important knowledge about the species and inform the twins on the ways they can help to care for the animals. After each mission, the twins are given tokens to track all of their efforts. Each location can be logged on your adventure map both at home and an interactive online portal.
