LGBT Fanbase: Predominantly due to many of Scary Godmother's friends being Ambiguously Gay. Scary Godmother also has a fair amount of fangirls.
Nightmare Fuel: In Revenge of Jimmy, the second time he attempts to cancel Halloween the Fright Side blinks out of existence. Scary Godmother is left stranded on her broom in a black void, with Skully, Harry, and Bug-A-Boo hanging on for dear life. Hannah manages to fix things, of course, but Fridge Horror comes into play when you think about what happened to everyone else in the Fright Side, including Count Max, Ruby, and Orson, when it ceased to exist.
Orson and Hannah seem to be flirting in a few scenes, confirmed in the book that Orson does have a crush on her.
Katie and Daryl. Daryl has a crush on Katie but it's ambiguous on her side.
Uncanny Valley: The animation has not aged well, with the character designs varying from a little unsettling to downright frightening. The models just seem so....off. Some of the most notable cases include the Black Bead Eyes on most of the human characters and the humanlike lips on Harry.
