4. 'The Nightmare Before Christmas' (1993)
Jack Skellington, also known as the Pumpkin King, is the reigning scare-meister of Halloween Town, bringing eerie chills to everyone in the world each October 31. But he craves something new, something different. So when he accidentally wanders into Christmas Town, he's bombarded with sights and sounds that he can't begin to understand, from snow to candy canes to The Man in Red himself. This sequence takes all the brightly-colored, sparkling-light, tinsel-strewn magic of the holiday and distills it into one musical number ("What's This?").
