It was the day before the extermination and Charlie told you to go do something with Niffty to help calm her down. Once you got to her room in the hotel, you knocked on her door and she told you to come in. As soon as she saw you, her psychotic grin widened, she was clearly thinking about stabbing the extermination angels the next day.
Niffty:"If I see an Angel I'm gonna stab it!" She laughed crazily
You walked up to her, trying to calm her down and suggested that you two do some arts and crafts to take her mind off of the extermination. She happily agreed. A few crafts in, Niffty made a little paper puppet of Adam, the head exterminator. She made a knife and a puppet of her to go along with it. She put the paper knife in her puppets hand and started to stab Adam's
Niffty:"STAB, STAB, STAB!" She laughs like a psychopath
