Ep 6. The House of the Lucky Gander!

When Gladstone Gander, Donald Duck's equally lucky and wealthy cousin, invites Scrooge and his family over to his luxurious mansion for a night of games and relaxation, Huey becomes suspicious of his cousin's motives. The normally reserved and cautious duck believes there's something strange about Gladstone's incredible streak of luck, and after he uncovers a secret door in their host's home, Huey and his siblings are thrown into an Indiana Jones-style adventure. As they search for hidden treasure and dodge booby traps, Scrooge and Gladstone's long-standing feud reignites, and Donald finds himself caught in the middle of the two squabbling relatives. Meanwhile, Webby, usually relegated to the background during such high-stakes affairs, takes it upon herself to investigate the mansion's ornery butler, who seems to know more than he lets on. Will the gang be able to uncover the secrets of the Lucky Gander and escape the mansion unscathed? Find out on this exciting episode of DuckTales!
