For Tiger, Wolf, and Bear ranks, a Cub Scout completes seven adventures as described in the youth handbooks. “Adventures” are collections of themed, multidisciplinary activities representing approximately three den meetings of engaging content. Six of the adventures are required and one is chosen from among 39 different electives, 13 of which are available to each of these ranks. Elective and required adventures may be undertaken at the same time. As the boys finish an adventure, they are awarded a belt loop that is worn on the official Cub Scout belt.
