Those considerate koala brothers Frank and Buster continue to assist their neighbors in this eight-episode collection of the popular series for preschoolers. The do-gooders buzz the Australian outback in their plane looking for anyone in need, and in this group of stories, they take on the daunting task of building a railroad track so their friend Sammy can ride on a real train. The boys also help out Archie, Ned, Mitzi and many other friends.
