I shall call him “Meat”

This is Meat. He is a bit of a nervous thing and really gets upset when the lights dim. Turn them off too quickly, and he screams. If he freaks out too much, he’s going to pass out and only a quick burst of light can wake him up.

Why is he afraid of the dark? Because there are monsters out there…

How does his little mind work?

With very messy code.
