Surprise Box

From: Mr. Black
Description: Delamode, all the buttons have been found. Why did you try to put us on the wrong track? I'll keep the buttons in a box for the time being. For example, this shiny one, held by the mannequin girl. I just need to unclench its grip, hand me some tools.
Completed: Hmm, the mannequin opened its hand by itself, I didn't even touch it. Monsters and Defenders, the mannequin opened the box and handed it to me, pointing at the buttons! Delamode, what's going on here? Is that a living mannequin?!
