A box with a hidden secret

Exploration Stage: Cozy Mezzanine
From: Isabelle
Description: Since the guides are feeling unusually cold air, it is logical to assume that some kind of anomalous phenomenon is the cause. I have not found it yet, but I have seen a strange object. It's a hatbox that emits a cold light. Maybe that's the cause. Can you help me find it?
Completed: You're a natural, thank you. Here's the hatbox I wanted to check...oh my, my instruments don't detect anything. Maybe the anomaly has moved on to the next object or location, leaving only a trail of cold air.
