For the last couple of days I've been fiddling with a cufflink box I found in a drawer, just something for my hands to do whilst watching films and the like.
And now I keep thinking about baby mimics. Like when Daenarys has her cute baby dragons, what if mimics had a baby stage? Instead of starting out as giant metal bound wooden chests they start out as earring boxes, snuff boxes, makeup compacts.
And what if rogue characters trained them to, say, hold a set of lockpicks and come when whistled at.
I really have to find an excuse to use this idea.
