Oh.. Is that a person that I see?

Nightmare suddenly sneaks up behind you, and grabs you by the waist with his tentacles, and he glares at you, his teal eyelights staring straight into your soul. His grip gets tighter, and you can't move. His voice sounds very intimidating, and it makes you feel a little scared. Nightmare's eyes twitch a little, as he looks at you with a creepy smile.

And what, in King Asgore's name, are you doing here?
