be vigilant

Exploration Stage: Abandoned Factory
From: Carlos Light
Description: Vila is a child who doesn't know how to relax. She's been that way since she was a little girl. I'm glad we're able to put her at ease. We'll install a special security bell in her hiding place. I thought I brought it with me, but I forgot where I put it. Can you help me find it?
Completed: You've already found the security bell! I made this one myself. It's based on a drawing that Vila did a long time ago. It contains a trained rat that can take notes on visitors and give them to Vila. That way, that little girl could see her guests only when she wanted to. No more uninvited guests!
