Underwater Adventure: Hal and Roger Hunt are scuba diving in the South Seas as part of an underwater operation collecting rare species for the Oceanographic Institute. They are exposed to incredible sights in the beautiful coral reefs of the South Pacific and go in search of hidden treasure in the sunken remains of an old Spanish naval ship. Sharks hungry for blood join them on several occasions in the water, but far more threatening is the presence of a crooked old school friend of Hal's with his sights set on stealing the treasure for himself. Safari Adventure: The Hunt boys have been enlisted to help stop a large and vicious group of poachers in the wilds of Tsavo National Park of Kenya. The boys are horrified to witness the ruthless killing and terrible maiming of thousands of animals, and are quickly also put in danger themselves. Their only hope is to track down the poachers' elusive leader, Blackbeard, before more animals are needlessly tortured and the magnificent wildlife of Kenya is lost forever.
