Analysis of SCP-3662 has shown that it stores SCP-3662-2 not as 
digital or physical information, but rather as an abstract meme 
complex, intersecting reality only at a one-dimensional point within 
SCP-3662. Information compressed this way is lossless, but 
subjects the meme complex to other memes within the Noosphere, 
which may affect the quality of the restored individuals. As the 
human mind is highly fragile in this state$, even a short amount of 
time in this form can cause severe damage to the individual upon 
recovery. As subjects are conscious within SCP-3662, psychological 
effects of isolation may also compound damage to the individual.

Interview Transcript 


Interviewer: Dr 


Interviewee: Laura Guerrero (occupying D-90832's 
vessel) 


Foreword: Ms. Guerrero was an inhabitant of SCP-3662 
for over a decade. Her mental faculties have degraded 
severely. She is capable of understanding speech and is 
capable of writing in a certain format, however, all traces 
of personality and ability to eat, sleep, see, vocalize and 
move any portion of the body other than the right arm 
have all been destroyed due to prolonged exposure to 
aberrant memes.

: Hello, Laura. Can you hear me? 


Guerrero: [Writing]: "Dear Diary#, [line break] Hello! Yes, 
! can hear you." 


: Excellent. Would you mind answering a few 
questions? 


Ms Guerrero keeps her pen hovering above the paper. 


: I'll take that as a yes. Why were you within the 
object? 


Guerrero: "/ don't understand you sometimes, Diary. 
What do you mean by object? Do you mean the clock, 
the one that the sad man pressed against my forehead?" 


: | do, yes. Tell me about the sad man. 


Guerrero: "/ knew the sad man. | saw him around the 
town all the time. His eyes were always droopy and sad, 
like he was always about to cry. He would never talk to 
people unless he had to. My Papa said that his daughter 
was very, very sick. So sick that she would probably 
never get better." 


: And what did this person do? 


Guerrero: "/ remember one day he was actually crying. 
He said that | reminded him of his daughter and that | 
would get along with her. After that, he pressed a clock 
to my forehead." 


: And what then? 
Guerrero: "/ got very tired but once | was just about to 


fall asleep | woke up. The first thing | felt was being 
washed away. Like my skin was being pulled apart and 


all the little bits would go flying off into the wind. " 
: What was it like in there? In the clock? 


Guerrero: [Brief hesistation] "It was lonely. There's 
nobody else in there and it's very dark. All the time you 
have this feeling like you're losing parts of yourself. It's a 
whole other world in there, Diary. It's always black but 
there's little... jellyfish-people. They glow and blob 
around unless you get too close, then they try to take 
away bits of you like an arm or a leg. [Uses right arm to 
point to other appendages] | got close a couple times." 


Guerrero: "/ was always running around, looking for a 
way out or for an adult to help me. Eventually, | gave up. 
There's no adults in there and there's no way out in 
there. | just [pause] sat down and cried until the jellies 
showed up. | didn't know what else to do." 


Guerrero: "Sometimes, I'd have time to look up at the 
sky. A starfish, a big bird, and a monster are all up there. 
| remember when Papa and | would get the telescope 
out from the shed and go up the little hill and see the 
constt konstt stars. [hesitation] Can | see Papa again 
soon?" 


: [Quietly, to colleagues] Do we tell her? [pause] well 
it's just that, to them, Laura only went missing for a few 
weeks? It's not like we can arrange a— [pause] Alright, 
fine. 

: Uh, Laura? Your family is fine. They... they can't see 
you right now. We're working really hard to find a way to 
get them to see you. 

Guerrero: "/ wanna see them." 


: We know, Laura.

March 1st, 1964 


Town Hero Saves Lost Girl 


Mr. Light, our very own electrician and town 
repairman, has recently been crowned as the 
local hero of ! After the safe return of 
Laura to her family, there's not enough time in 
the day to say how thankful we are. 


Laura Guerrero, 7, (pictured) was recently 
kidnapped. It goes without saying that the 
Guerrero family was shocked to slowly come 
to the realization that Laura would not be 
returning from school that fateful February 9th. 
No ransom notice was given. Even with police 
investigation, no leads were found to 
Guerrero's whereabouts. 


Laura was escorted to school, as usual. She 
was present on the register, as usual. When 
the home bell rang, Laura didn't return home. 
Laura says she has no memory of the event. 
The only thing about the whole ordeal she 
remembers clearly is that Mr. Light was the 
one who found and saved her from her 
captors. Psychologists say she's repressed the 
memories and there's no telling what horrors 
she experienced. Guerrero's family also note 
that Laura has been acting more meek and 
timid than before, which the psychologists 


XO: It started to fall apart from the inside. Screws, bolts, 
nails in the damn furniture... it all started getting knocked 
out or unscrewed. Even some of the stuff welded in 
place. The voices got bad too. And the bastards were 
always so matter-of-fact and calm, even while they were 
rattling the ship all to hell and taking everything apart. 
One of them was talking about all the great things he 
could show me. Another was gibberish | couldn't make 
out, but she was pissed. We could all hear the voices, 
there were just no bodies to go with them. It got hard to 
tell which voices were our crew and which were the 
damn... whatever they were. 


Dr. Halen: When was the last time you saw Captain ? 


XO: He gave the order to turn around and told me to 
handle things on the bridge while he checked something 
below deck. | didn’t know he was missing until after | 
gave the order to abandon ship and everyone was in the 
rafts but him. God if that’d only been the end of it... 


We started rowing away from the wreck and we heard 
him yelling for help. It was far off, toward the shipwreck. 
He and | served together for years, we helped bring in 
SCP- ,| Knowit was him. | figured he’d gotten knocked 
overboard or something. And | gave the order for a raft to 
go get him. Watched them get close to the horizon, must 
have been 2 or 3 kilometers from the shipwreck when 
they just went under. No sound to it, like a kid’s bobber 
getting pulled under by a fish on the line. I’ve seen men 
die, but | know | sent those guys someplace a lot worse. 


Wasn't long after that that Daniels started whispering to 
me about what a bastard | was, how | sent them all to die 
for nothing. He said the only way to make it right was to 
jump out of the raft and join him. Maybe | would have 
too, if not for the other guys on my raft. We spent hours 
rowing, with our friends screaming for help behind us. 


Even when they were far behind us, they didn't stop 
whispering in our ears. My friend told me it was the 


have called a symptom of her stress. 
Hopefully, in time, Laura will return to her 
vibrant, playful self. 


After two weeks of little Laura's 
disappearance, the Guerrero family had given 
up hope. We can only imagine the despair and 
grief they would have experienced in that 
troubling time. 


Seemingly out of nowhere, Mr. Light came to 
the Guerrero household with, cradled in his 
arms, the delicate form of little Laura. He 
states that he heard some hushed voices and 
muffled cries for help in the night, grabbed his 
rifle and went to investigate. There, he saw the 
group of absolutely vile kidnappers and took 
action: firing with accuracy and grace causing 
her captors to flee, leaving Laura behind. 


But, as God giveth, God taketh away. The 
price for one child's life seems to have been 
paid with the blood of another: Mr. Light's own 
daughter. Emily has recently passed away. 
The Guerrero family have paid Mr. Light's 
funeral expenses in full, and the town has 
raised a fund to serve as both a symbol of our 
gratitude and our condolences. We, the writers 
at the , have chipped in $100 and 
encourage you to do the same. 


Emily was sickly from birth. She had a 
congenital condition called hemophilia, a 
disease with no known cure. The lifespans of 
these individuals are severely reduced. 
Children are bed-ridden and adults much 
watch themselves carefully. It's a cruel twist of 
fate that a brave person like Mr. Light has to 
burden such grief; if Emily's body were normal, 
she would still be alive today. I'm sure that 
she's smiling down on our little town from the 


heavens. 


Luckily, things are going well for Mr. Light, all 
things considered. Laura often visits her hero 
and Mr. Light has taken a paternal role for 
Laura. While life may never return to normal 
for these two, we can only wish them the best. 
Here's to Mr. Light and Guerrero family for 
their acts of bravery and kindness beyond the 
call of duty.

SCP-3663: The Adventure of the Cardboard Box 


SCP-3663's containment zone. Entity not pictured. 


Item #: SCP-3663 
Object Class: Euclid Keter 


Special Containment Procedures: SCP-3663 is currently located 
in what were formerly the Site-54 maintenance tunnels. To prevent 
demanifestation, no personnel are to be given access to the area, 
and efforts are to be taken to reduce the tunnels’ moisture levels. 


Should SCP-3663 demanifest, MTF Nu-4 ("Box Cutters") are to be 
mobilised, with the goal of a) locating SCP-3663 and b) preventing 
any damage occurring to the entity. If possible, SCP-3663 is to be 
fitted with GPS tracking devices to aid re-containment. Once 
located, SCP-3663 is to be transferred to a mobile pipe network, and 
remanded to Site-54. 


Efforts are to be undertaken to discourage SCP-3663 from 
transporting itself to a location within two kilometers of SCP-015. 


Description: SCP-3663 is a humanoid entity constructed primarily 
from cardboard (in the form of boxes and tubes), adhesive tape, and 
twine. SCP-3668 is fully capable of movement and vocalisation via 
an unknown mechanism, and has proven to be semi-sapient, 
responding to questions and reacting to its immediate environment. 
The interior of SCP-3663 contains crude cardboard and paper 
models of all major human organs, with coloured wool representing 
blood vessels and the nervous system. SCP-3663 does not require 
these components to function, and their purpose within the entity is 
unknown. 


SCP-3663 is capable of instantaneously transporting both itself and 
other objects over long distances, with no upper limit to the entity's 
range observed. The method by which this is achieved is currently 
unknown, though it is known that physical contact with the entity is 


required. Despite being able to utilise its abilities regardless of 
physical location, SCP-3663 has shown extreme preference for 
3663-Applicable regions (defined as an enclosed, tunnel-like space, 
or network of spaces, measuring at least 40 cm in diameter), and 
will invariably choose to manifest within such areas. 


SCP-3663 behaviour is easily predictable when not influenced by 
outside forces. The entity will engage in a simple cyclic pattern of 
actions, which have been recorded as follows: 


1. SCP-3663 manifests in a 3663-Applicable area, emitting low 
vocalisations and waving its arms in a manner suggesting 
attempted intimidation or fright. The entity will begin roaming 
the area, pausing periodically to emit louder, higher pitched 
noises. 

2. SCP-3663 will attempt to make its way towards any human 
subject in the area. Note that if no subject is nearby, this 
action will not commence, and SCP-3663 will simply remain in 
the area indefinitely. Rarely, SCP-3663 has been observed 
pursuing subjects outside of 3663-Applicable areas, to a 
distance of (at most) 50 metres. 

3. The subject is gripped by the entity, and experiences 
heightened apprehension and/or paranoia. SCP-3663 
demanifests. 

4. SCP-3663 manifests in a second 3663-Applicable location, 
along with the subject, who is invariably unconscious but 
otherwise unharmed. After releasing the subject and moving a 
short distance, SCP-3663 demanifests a second time, 
reappearing in a third location and triggering the beginning of 
a new cycle. 


If at any point during this cycle SCP-3663 is damaged in such a way 
as to inhibit movement, or is moved more than 50 metres away from 
a 3663-Applicable area, it will instantaneously demanifest, returning 
to the beginning of a new cycle in a repaired state. Small damages, 

such as minor cuts or tears, will not trigger this effect.

> Show Interview Log 


Interviewed: SCP-3663 
Interviewer: Researcher Doyle 


Foreword: The following interview was 
conducted via two-way audiovisual recording 
systems embedded within a makeshift 
interview chamber, located inside SCP-3663's 
central containment area (formerly the Site-54 
maintenance tunnels). 


<Begin Log> 


Researcher Doyle: Hello SCP-3663, | was 
wondering if- 


SCP-3663: The... the tunnel monster. 
Researcher Doyle: I'm sorry? 


SCP-3663: I'm the tunnel monster. Not... not 
SCP 3663. The tunnel monster. That's me. 


Researcher Doyle: |... see. So, uh, tunnel 
monster, why do you do what you do? Moving 
people around, | mean. 


SCP-3663: The tunnel monster captures 
people. That's me, I'm the tunnel monster. I... | 
capture people and take them into the tunnels 
where | live. In the tunnels. The pipes. I'm the 
tunnel monster. 


Researcher Doyle: | understand that, but 
what do you hope to achieve by doing it? You 
seem to pick your locations at random, so it 
seems to me that you're not really making 
much of a difference. You could just as easily- 


SCP-3663: Please stop. It's what | do, | have 
to do it, I'm not... | am the tunnel monster. It's 
me. Please stop. 


Researcher Doyle: What? We're trying to 
help you here, you can't want to spend all your 
time underground. We can get you set up here 
with your own room, you wouldn't even have to 
crawl about in those dirty pipes anymore. 
Doesn't that sound nice? What do you say? 


SCP-3663: Please. I... I'm the... [SCP-3663 
pauses for ~5 seconds] ...the tunnel monster. | 
don't want to... to do this, it's what | do. | have 
to do it. I'm the tunnel monster. | do it, I'm the 
tunnel thing, the tunnel monster. [Two wet 
patches are observed forming on SCP-3663's 
'face'] In the pipes, hiding in the tunnels going 
to get you. | have to do it. Please. [SCP-3663 
front surface begins to lose structural integrity 
due to accumulated water damage] Please. | 
don't want to play anymore. I'm the monster. 
The tunnels, I'm [unintelligible]. 


Researcher Doyle: ... That will be all for 
today. Thank you. 


<End Log> 


Due to the possibility of severely damaging SCP-3663, to 
the point of initiating a new cycle and a breach of 
containment, no further interviews are being scheduled 
for the foreseeable future.
