You're a hitman. You were hired to kill someone named... "A Monsterling?" Weird. You couldn't bother to ask questions, so you grabbed your weapon and drove to the address given to you.

You knock on the door, but it's already open. Stepping inside, you felt the wall to look for a light switch, but it doesn't work. Assuming that nobody's home, you turn to walk out the door, but it's nowhere to be seen...

You hear a strange voice murmuring from all around you.

"Could I just get a little piece...?"

What do you do...?
