I guess I'm lazy cause I don't wanna look through all these pages but how do the eyes move exactly? I don't get how you could move them.
It's not known for sure, but one method out there which looks likely to be the case for HT is that there's a small hole in the pupil that you stick a pin into and move them.
What has me curious is how they're connected so when you move one the other goes with it, and how breakable is this.
