Special Filling

Exploration Stage: Compartment No. 8
From: Detective
Description: A guy like Doubledeal may have easily pocketed some forbidden artifact without realizing its real danger. People like him steal everything they see. Next on the list of prohibited artifacts is a stash cane. Can you help me find it?
Completed: Great, buddy, you’ve found the stash cane! It has some kind of special mineral granules in it. If I’m not mistaken, it’s great at removing fingerprints, so it’s often used by criminals. Let’s check. Ha, I was right, this thing erased my fingerprints in an instant!
