When he gets his first job as a shoe shiner, his first customer presents him with extremely filthy work boots, but pays him with an American coin (a dime).
While exploring the castle, Scrooge discovers that the hound only was a trick by the Whiskervilles, who wanted the McDuck family out of the way so that they could steal the hidden treasure.
Encouraged by a strange keeper in the castle, Scrooge gets revenge for his family by filling a suit of armor with peat and setting it on fire, scaring the Whiskervilles into thinking it was a ghost.
After Scrooge leaves the castle, the keeper reveals himself as Quackly McDuck, the ghost of the ancestor who was sealed away in the wall.
When asked by the ghosts of the other ancestors why he didn't simply just show Scrooge the location of the treasure, he explains that the boy must earn his fortune himself.
