At the same time, Jo, Zette and Jocko are walking on the beach and get into a row boat but get lost in the fog. They are then picked up by a ship and have no idea of the adventures that await them (Manitoba no reply)... ...Jo, Zette and Jocko, after escaping from the ship run by the scientist, find themselves on an island where they are pursued by pirates (The Eruption of Karamako ).
