empty hand

Exploration Stage: Traveling Circus
From: Angelique
Description: We don't have much time, so let's continue our investigation of the ventriloquist's trailer and find out if the dummy doll was made by the puppeteer. It is a good idea to look at the dummy's spare parts. If the doll is of simple construction, it will not have a complicated mechanism. Can you find any?
Completed: So you found a dummy doll hand. Oh well...this is not a hand, but appears to be just a glove with a jointed joint. I have never seen something like this used in mannequin production! There doesn't seem to be any mechanism on the inside...am I missing something?
