The problem is having everyone respond to it, as well as accounting for the fact that you can't talk, see, or do anything with your face! It's way more work than you think!
For gross solution is that the meat parasite penetrates your eye hole and connects with your eye nerve directly so you can see. For normal solution is that there are some gaps between the parasite so you can see through. For talk, the meat parasite only fuck your face and lay eggs in your mouth and stomach when it feels like it, so you can talk when it is happy.
