Hot Spells is the only banned episode of Darkwing Duck, aired on Halloween, 1992. It features a trip to Morgana's "Poison Ivy"-league school, where Gosalyn gets the keys to library of forbidden spells - from Beelzebub himself. The idea of Gosalyn practicing Satan's magic was enough to get the episode buried. Check Disney Plus, you won't find it. Never mind the fact that Beelzebub was previously seen in one of the greatest episodes, "Dead Duck." Never mind the fact that Morgana has always been a part of the show. What the hades was Disney's "Night on Bald Mountain"? Chernabog has long been seen as the devil himself, and all of Disney's villains have been doing his works - from Grimhilde to Scar, and, as Beelzebub says in this very episode, Darkwing's own rogues gallery.
This episode is filled with the kind of jokes that make Darkwing Duck Darkwing Duck. The dramatic music that plays every time the library is mentioned, the snappy stuff like Yorick having a bone to pick - the fact that his name is Yorick will go over most kids' heads, and many of the more educated parents will get a smile out of it. Morgana, as a witch or sorceress, is the perfect match for Darkwing - the darkness of her nature matches DW's (look at his name). She's just lacking his ego, but now we know (if we didn't already) she's not evil. Morgana's not at her best here, but it's colourful to enter into her world.
