"Wait, what?! That's terrifying, I have to be careful..." "But there's a way to be saved. The 1st is always short on meat, so if you come to school at night, you should bring some.

If you peek inside, you'll see the 3rd staring at the screen with a terrifyingly expressionless face, illuminated by the pale blue light.
