Hide tiny rubber or plastic jungle animals in your jungle (meeting area).  Or you could you use animal crackers.  Divide the boys into groups and have one Cub be the safari guide.  Each group is given an animal name - bear lion, monkey, and snake.  On your signal the team of hunters go on their safari looking for their animals.  When they find their assigned animal, the hunter makes his animal sound (growl, chatter, hsss etc.)  and then waits for their guide to come capture the animal in their team cage.  Use a margarine container decorated in camouflage colors.  Cut a circle out of a clear lid to within 1/2" of the rim.  Cover the top with netting and secure under the rim.)  The Cubs continue hunting animals, making their sounds and having the guide capture the animals for a designated time.
