Generica's holiday outfit is a reference to the outfit worn by Jack Skellington, the main character of the 1993 stop-motion animated film "The Nightmare Before Christmas". When given said outfit, she'll state "What's this? What's this? This outfit reminds me of a nightmare I had once, just before Christmas.", which not only alludes to the film's title, but also to the song "What's This?" from the film, which is sung by Jack when he first arrives in Christmas Town.
