“Why should Christmas get all the cool sweaters???” -Mabel Pines probably
The episode would end with it dangerously heating up after the final candle is lit. She would then have to throw it at the monster of the week, where it would erupt into flames like a deus ex machina IED. We would learn an important lesson about family or friendship or trust or whatever, and also probably something important about not wearing clothes with batteries in them. It would be immediately replaced by a glittery back-up sweater so reflective and shiny that everyone in a 20 yard radius would be blinded trying to look at it. I can see it in my mind
