There was, as yet, no established convention for the same character having different adventures in the Sunday strip and the daily strip (many newspapers carried one but not the other), so the Sunday strip at first followed the adventures of Buck's young friend Buddy Deering, Wilma Deering's younger brother, and Buddy's girlfriend Alura, later joined by Black Barney.
