Theirs is going to be a scarf. They've never worn one before, but those're supposed to help with cold, so this pink tinsel must do that too. Must be there to keep the trees warm now, but Frisk needs it more!

They hum an I-don't-know. Somewhere in a part of the city they haven't been before, they guess. And tail-kid too.

Thinking of that tail, Frisk's eyes lock onto it. He's not paying attention...

Once their tinsel-scarf is situated--it's kind of itchy--they start creeping up behind him. (Badly. They aren't light on their feet.)
