Scrooge McDuck wants to find the treasure of King Duckapulco, an ancient ruler of a pre-Columbian South American empire. But the King’s ghost demands his vast wealth go only to the pure of heart. Is that why Scrooge and Donald are bringing Huey, Dewey, and Louie along? Beyond “King of the Golden River,” this collection of stories, in English for the first time, includes “Me, Myself, and Why” — in which Scrooge adopts two aliases to confuse the taxman — only to develop a real split personality! Plus: The Wild West saga of “Mickey the Kid and Six-Shot Goofy!”
