Thanks for the feedback, and no, it is not an "andalite", whatever the hell that is. To google!
*after googling* Wow, no, I have never seen those before, but they are creepily similar to what I have in my head, so I might go change that.
I think you may be right on the thing speaking in a language we can understand. I'll play around with it and see if I can't make it work a little better to add to the creep.
You also raise a good point Adam with the scaffolding thing. I don't think I will take it quite that far, but I will add something about all tests being performed in a sealed chamber, and something about quarantining all present personnel and organisms that come through.
