Mrs. Beakley is abducted by Vikings from Norse Mythology and it is up to Scrooge and the others to rescue her.
This episode contains examples of the following tropes:
- All Part of the Show: Mrs. Beakley was performing when some real Vikings showed up and abducted her. They were gone before anyone realized it wasn't part of the show.
- Glass-Shattering Sound: Mrs. Beakley uses her opera singing to bring down an avalanche, letting her racing team cross a crevasse.Mrs. Beakley: If the sound of a horn can do that, what would a C above high C do?
- Going Commando: Swanwhite wears nothing but tailfeathers underneath her skirt, but dons footwear.
- Leitmotif: Wagner's Ride of the Valkyries (with wordless lyrics) is what Mrs. Beakley is singing when the Vikings appear, of course. Its instrumental version is then used for much of the soundtrack of the episode.
- Lost World: The island where the Vikings live (cut off by ice but heated by volcanoes and hot springs so as to have flora and fauna) is implied to be this, to explain how Vikings could exist in the present day.
- Poisoned Chalice Switcheroo: Inadvertently invoked, but also downplayed. Queen Griselda, jealous of Mrs. Beakley for her husband's infatuation that led to kidnapping her, decides to remove her from the picture by removing the thing that drew her husband in: her voice. After putting a potion in a glass of water and trying to figure out how to get Mrs. Beakley to drink it, the duck in question shows up—except she wanted it for Launchpad, who had gotten extremely nervous and thirsty over the upcoming race. End result, he loses his voice and, since the voice is required to make the sled team go, Mrs. Beakley has to go instead in disguise as a man. This ends up being critical as it's her voice that lets her win (see Glass-Shattering Sound above).
- Thoroughly Mistaken Identity: Mrs. Beakley would like it very much to be known that she is not Brunhilde! (Although she's not above using the king's confusion to get preferential treatment, or learn of rules and laws she can use to help her and the others escape.)
