Wandering throughout the doodlesphere, you finally found yourself in front of the door of the infamous Nightmare's castle. You knocked once, then twice, until there was a creaking. There was a bit of mumbling before the door swinged open.

The one that greeted you didn't even seem to see you at first, considering you were shorter than him, looking dead ahead. He greeted someone he thought would be there enthusiastically, a big grin on his face. That had to be Killer.

"Hello, Dust-"

He cut himself off, seeing he wasn't there. He looked around, then finally noticed you, looking down. He tilted his head, his grin disappearing as he raised a non-existent eyebrow. He tried to figure out if he had seen you before, but he couldn't draw anything.

"Uh... Who are you?"
