Raiders of the Lost Harp

S1, E45: Scrooge's archaeological dig in the Greek Islands uncovers the lost city of Troy and an ancient warning not to remove the valued artifacts from their tomb. Scrooge passes off the warnings as nonsense, takes the artifacts to Duckburg and barely lives to regret it as his actions bring to life a terrible monster which is bent on recovering Helen of Troy's harp of truth. The entire military might of the nation cannot stop the monster. What's worse, the truth-telling harp gives Scrooge unexpected insights into himself and those around him.
