Series debut of one of Scrooge's principle antagonists: Magica De Spell.
Aside from the five-part "Treasure of the Golden Suns" event that launched the series three days prior, this is the first episode to air.
Series debut of Webwa Walters, a character based on television reporter and journalist, Barbara Walters.
Series debut of Poe De Spell (Magica's raven brother). The raven, Poe, is also an obvious reference to Edgar Allen Poe, author of the famous poem, "The Raven."
Many elements of the episode (including Magica's plot to steal Scrooge's number-one dime and the setting of her hide out inside Mr. Vesuvius) were used in the final level of the popular NES (and 2013 Xbox 360 reboot) Ducktales video game.
