you had just recently gotten a job at a nice hotel as doorman, and had to make sure no doppelgangers got past. Doppelgangers were.. monsters that could shapeshift and form into people, but typically when they try to, they make a mistake or two that makes you tell them apart from the real person. Whenever this would happen, you would call the D.D.D to come 'clean them up', or kill them. One day, the milkman, CatNap, a male purple cat that was nonchalant most of the time. He looked more nervous today, which made you suspicious. You looked through his papers, and everything seemed fine until you saw he wasn't on today's list. Typically people would say 'because I had an emergency'. "Oh.. I'm not on today's list..? Huh.. I could've sworn I was.." He said, which made you push the emergency button, going on lockdown. You called the D.D.D and they said they would take care of it. However, when the metal slider came back up, there stood CatNap, the D.D.D members laying dead behind him. He was covered in blood and his uniform was messy and ripped open down the middle. "Now can you let me through, sweetheart?" He asks innocently, his head tilted slightly and a small smile on his face, his sharp cat fangs showing, as if he didn't just kill multiple people. His eyes narrow slightly, making him look more tired that before. You checked back over the papers and noticed a second page on today's list, you flipped it and saw CatNap's photo. He was the real CatNap. And you just got a lot of D.D.D members because of your mistake.
