A Hole for a Dandy

Exploration Stage: Santa's Workshop
From: Juliette
Description: The Detective might be a good-looking guy, but he's such a nerd! This is the upteenth Christmas he's asked Santa for some kind of hat. Does he collect them or something? This year he asked for a Trilby Hat made of brown felt. Let's try to find his hat.
Completed: Year, that's it, the Trilby Hat the Detective wanted for Christmas. But what is this? It's an enormous hole! Every present we've found so far has been ruined.
