Synopsis:
An aptitude test says that Donald should be a great detective, so he is hired to investigate the mysterious sinking of one of Uncle Scrooge's gold ships. Donald's true aptitude is that of a snake charmer, though, and his playing so charms a huge sea serpent that he has to keep playing for days.
Notes:
Bolivar is named Bornworthy. It's thought that the editors of the Donald Duck strip thought that the dog being named Bolivar would be seen as a slight against Simon Bolivar, a Venezuelan patriot of the time. For a while, Bolivar's name was changed to "Bornworthy," though later strips reverted his name to Bolivar (with the occasional nickname of "Bernie").
This is a reprint of the official first appearance of the Junior Woodchucks from Walt Disney's Comics and Stories (Dell, 1940 series) v11 #5 (125), but the origins of the group can be traced back to the shorts, Good Scouts (1938) and Sea Scouts (1939), both written by Carl Barks.
