The Wooden Ship is a map leading to treasure. It was first seen in the pilot, Don't Give Up the Ship.
Later, El Capitan frees the Beagle Boys from jail to help him obtain the ship. They steal it, and the nephews are blamed for its disappearance, since they had shown interest in it earlier and Scrooge did not see the Beagle Boys in time. Later in their hideout, the Beagle Boys hesitate to hand it over, demanding to know what's so special about it. El Capitan finally admits that it leads to a treasure, but the nephews arrive having worked out where their hideout is and take it back, hearing everything.
They lead them to Scrooge's Candy Factory, where a struggle breaks out, though not before the nephews explain why the ship was so important. When Bigtime Beagle captures Huey, Scrooge agrees to hand over the ship in exchange for his nephew. When Bigtime releases Huey and takes the ship, Scrooge hurries them away while Dewey and Louie tip over a vat of chocolate onto them. The ship sticks to the chocolate, and Scrooge pulls it away, leaving an indention.
