Per 
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be kept in a standard humanoid containment chamber. The exit of SCP-XXXX’s chamber must be equipped with motion sensing devices, and be watched by no less than two personnel of level 2 or higher clearance at all times. Given it’s temperament, SCP-XXXX is to be given any item it requests provided the item could not be used to compromise security. To date, SCP-XXXX has requested:
- Several plush toys (Granted)
- Several small Halloween decorations (Granted)
- A coloring book and crayons (Granted)
- A Nintendo 3DS (Granted, however internet access on the device has been disabled)
- A pumpkin carving kit (Denied)
SCP-XXXX must be given candy or sweets of some kind every day, as that is all SCP-XXXX will eat and it does not seem to have any negative health effects on them.
Containment Procedures Addendum: Annually, on October 31st before 8:00 pm, SCP-XXXX must be transported to an isolated, dummy town from 8:00 to 12:00 to prevent SCP-XXXX from escaping. See Incident Report 10/31/██.
Description: SCP-XXXX is a humanoid entity of indistinguishable gender and race. The entity measures roughly 1.1 meters in height. SCP-XXXX’s appearance changes periodically, however it is always seen wearing some sort of Halloween costume. It is unknown where SCP-XXXX gets these new costumes from nor where the previous ones go upon removal. SCP-XXXX has never been observed changing costumes and only does so when there is no direct line of sight between the entity and any person. The costumes have a wide variety, but they all seem to include a mask or accessory of some sort that obstructs the face. SCP-XXXX cannot be seen or detected through any sort of video recording device. Despite this, SCP-XXXX appears uncomfortable or anxious whenever a camera is pointed at them.
SCP-XXXX is capable of human speech and is usually quite talkative, however it has trouble reading and writing. SCP-XXXX also communicates in a very childish way; they pronounce certain things wrong, they have trouble with more complex words, etc. SCP-XXXX does not seem to require sleep, instead it enters a state of inactivity for 7 to 8 hours every day around 10:00 am. During this state, SCP-XXXX stands upright, completely immobile, usually in a corner or in the very center of their cell. Interrupting them in this state causes them to become irritable and even hostile toward personnel in some cases.
At exactly midnight every day, SCP-XXXX will enter another state referred to as “trick-or-treating”. In this state, SCP-XXXX will approach the nearest human individual, hold out a container of some sort (the type of container seems to correspond to whatever costume SCP-XXXX is wearing at the time) and say “trick or treat”. If no subject is in the vicinity of SCP-XXXX, it will begin to seek out one by whatever means necessary, including teleportation. SCP-XXXX will continue to follow the subject, repeating “trick or treat” until it receives sweets of some kind or 1 hour passes. In the latter scenario, SCP-XXXX will appear upset and enter it’s “inactive” state. Within the next 30 to 45 minutes, the subject SCP-XXXX was perusing will die of seemingly unrelated circumstances. The death of the subject is different with every instance, however the cause of every death is always, in some way, related to the costume SCP-XXXX was wearing. After the death of the subject, SCP-XXXX will come out of it’s inactive state and [DATA EXPUNGED]. In the event that the subject does not leave any remains, SCP-XXXX will return to it’s “trick-or-treating” state, and seek out a new target.
Incident Report 10/31/██: On 10/31/20██, SCP-4XXX began knocking on doors and “trick or treating” around Site ██. It is unknown how SCP-XXXX escaped it’s room undetected. SCP-XXXX acted similar to it’s “trick-or-treating” state, however it only waited 2 minuets for candy and attacked subjects directly when not given any. Since most personnel were not expecting to see SCP-XXXX and therefore had no candy available, this event led to the death of ██ personnel before SCP-XXXX could be properly re-contained.
Interview Log 1: The following is the fist interview conducted with SCP-XXXX:
Interviewed: SCP-XXXX
Interviewer: Dr. █████
Foreword: First attempt at communication with SCP-XXXX, Dr. █████ attempts to gather information on the entity.
<Begin Log>
Dr. █████: Hello, XXXX.
SCP-XXXX: …
Dr. █████: XXXX? Can you speak?
SCP-XXXX: Who’s XXXX?
Dr. █████: Sorry, let me start again. What is your name?
SCP-XXXX: My name?
Dr. █████: Yes, your name.
SCP-XXXX: (Pauses) I… I don’t think I have a name.
Dr. █████: Oh, well, is there something you want me to call you?
SCP-XXXX: (Pauses) How about… Jack.
Dr. █████: Jack?
SCP-XXXX: Yeah, like Jack the Ripper, or Jack Skelington, or Captain Jack Sparrow.
Dr. █████: I see… Well Jack, I have a few questions for you. What’s the earliest thing you can remember?
SCP-XXXX: The earliest thing? (Scratches their head) Earliest… thing…
Dr. █████: Can you remember anything?
SCP-XXXX: Hang on, I got it, I got it. (Thinks for a minute) Ok, so I was in my village trick-or-treating. It was real late, so lots of people had gone to bed, and I was looking for someone who was still awake.
Dr. █████: Why were you out so late?
SCP-XXXX: I really like Halloween. I wanted to have as much fun as I could before it was over.
Dr. █████: Well, what I mean is, didn’t you’re parents give you a—
SCP-XXXX: (Seems upset) I don’t wanna talk about my parents…
Dr. █████: I mean, surely they—
SCP-XXXX: I said I don’t wanna! (Slams their head down on the table)
Dr. █████: (Pauses)
Dr. █████: Sorry, please continue.
SCP-XXXX: (Lifts their head up) Ok… So, I was looking for someone still awake and I saw someone standing right before the woods.
Dr. █████: Now this figure, were they an adult, a child? Describe them please.
SCP-XXXX: They were… (Pauses) kinda creepy. They were really tall and they were wearing all black stuff. I couldn’t see their face and (Pauses) It kinda hurt to look at them.
Dr. █████: You said they were creepy?
SCP-XXXX: Y-yeah, but (They begin speaking faster) it was Halloween s-so I just thought i-it was a costume so I… I, uh… (Begins fidgeting with their hands)
Dr. █████: You approached them?
SCP-XXXX: (Looks down and nods)
SCP-XXXX: (Long Pause)
Dr. █████: XX— Jack, can you please tell me what happened?
SCP-XXXX: (Sniffs) Y-yeah (Voice is very shaky) I asked him f-for candy, like I d-did with e-everyone else. He looked down at m-me and asked me if I l-liked Halloween, and I s-said yes. Then he asked me i-if I wanted Halloween t-to last forever. (Looks up at Dr. █████) That w-was all I ever r-really wanted, Halloween was when I w-was the happiest… So I s-said yes, and th-then they… they, uh…
SCP-XXXX: (Slams their head down again) I c-can’t remember! M-my head hurts!
Dr. █████: (Pauses) That’s alright. Jack, you’re alright. That will be all for now.
<End Log>
Closing Statement: SCP-XXXX remained with their head down for just over 14 minutes before being calm enough to be returned to their room. Further testing should be dealt with in a more gentle matter.
Interview Log 4: The following interview was conducted the day after the events described in Incident Report 10/31/██.
Interviewed: SCP-XXXX
Interviewer: Dr. █████
Foreword: SCP-XXXX was brought in to be questioned about the events in Incident Report 10/31/██.
<Begin Log>
Dr. █████: Good Evening, Jack.
SCP-XXXX: You’re gonna yell at me, aren’t you?
Dr. █████: No, I’m going to ask you why you did what you did
SCP-XXXX: And then you’re gonna yell at me.
Dr. █████: Jack, no one is going to yell at you.
SCP-XXXX: You promise?
Dr. █████: Promise. Now, why did you leave your cell yesterday?
SCP-XXXX: It was Halloween, and I wanted to go trick or treating.
Dr. █████: Yes, that much is clear, but why do you get so violent when people don’t celebrate Halloween?
SCP-XXXX: I just… I don’t get why people wouldn’t want to celebrate it. Halloween is literally the best day of the year! (Starts getting agitated) I told you last time that I [DATA EXPUNGED] for Halloween, and some people just act like it’s any other normal day!
Dr. █████: Jack, please calm—
SCP-XXXX: I had to go through so much [EXPLETIVE REDACTED] for this holiday, it’s all that I have, and some people just act like it doesn’t matter! It just makes me—
Dr. █████: Jack! Calm down, or you will be removed from this interview!
SCP-XXXX: I don’t even wanna be in your stupid inner-view!
Dr. █████: Then we are done here.
<End Log>
Closing Statement: SCP-XXXX seems to have grown much more irritable since they were brought into foundation custody. Further testing will be postponed until a solution to SCP-XXXX’s hostility can be found
Note: A proposal has been made to utilize SCP-999 to subdue SCP-XXXX’s anger during interviews.
Test Log: The following is a record of certain tests of SCP-XXXX effects when in their “trick-or-treating” state.
