When Scrooge swaps places with Giorgio Cavazzano’s “Brother From Another Earth,” he winds up in a scary parallel Duckburg! Magica sics a spook on Scrooge in Frank Jonker’s “Spirit of Fear”; then Scrooge battles a giant robot in Lars Jensen’s “Synthezoid from the Deepest Void!” Finally, in Carl Barks’ “That Small Feeling,” Gyro Gearloose meets the witch doctor, and gets his head shrunk before you can say ooh-ee-ooh-ah-ah!
