This is the only episode omitted from the show's US digital release despite being available for purchase in Germany.
Darkwing and Gosalyn go with Morgana to her old magic alma mater, where Morgana is to present her paper on a profound magical breakthrough. While there, Gosalyn is allowed to participate in some classes because of her natural affinity for the unnatural; but quickly finds the underpinnings of magic, complex mathamatics, too boring for her tastes. Bored because getting used car salesmen and politicians aren't a challenge. Bielzebub finds out about Darkwing and Gosalyn being at the school, and decides this is his chance to move up in the rankings of top villain-by getting Darkwing once and for all!
Gosalyn tries to find a short cut to learning magic without the hard math involved, but is hoodwinked into using forbidden spells when Beelzebub disguises himself as the school janitor. By using the forbidden spells she allows of Beelzebub to steal Darkwing's soul. Can Gosalyn and Morgana find some way into tricking him into letting Darkwing go?
- This episode featured a cameo of the Magic Brooms from Fantasia.
- This was one of four Darkwing Duck episodes that was banned after its initial airings (the other three being "Tiff of the Titans", "Bearskin Thug", and "Aduckyphobia").
- However, unlike the other three banned episodes, "Hot Spells" has never seen a release on VHS or DVD and is the only episode unavailable for digital purchase on iTunes and Disney+.
- Strangely, clips from this episode were used in at least one promo advertising the series in syndication in 1993.
- Beelzebub previously appeared in "Dead Duck" (which, oddly, was not pulled from reruns like this one was). The Devil also makes a "twin" cameo as accountants for "Dizzy Studios" in "A Star is Scorned".
- The very fact that a Disney-related show had a character that closely resembles Satan (and was even allowed to air a few times) is unusual.
- In this episode, we get to see many of the monsters and magic that make up Morgana's world.
- The creature that Gosalyn summons was called a "Gulerian Taronga". It was modeled after Lena Hyena from Who Framed Roger Rabbit. The first name was from Greg Guler, and the last name from a fan mailing list that Tad Stones was a member of, hosted at taronga.com.
