IK-638, and to secure the retrieval and removal of listed artifacts of 
cultural or historical value, before attempting to evacuate 
themselves. Mobile Research Unit 638 is to remain on site within the 
Gold Zone and transmit observations and data to Overwatch 
Command until such time as environmental conditions render 
communication impossible. Following Event 638-Mu-34, the 
Foundation is to liaise with national governments and employ its 
resources for humanitarian purposes as necessary to prevent 
escalation to an IK-class collapse-of-global-civilization event. 


Description: SCP-1238 is a species of deep-sea fish with no 
current taxonomic classification, morphologically similar to the 
Antarctic toothfish (Dissostichus mawsoni). SCP-1238 resides 
principally in deep waters in the northern Pacific Ocean, along the 
northwestern American and western Canadian coastlines. Adult 
SCP-1238 specimens measure on average 1.4 meters in length and 
weigh 100-110 kg. SCP-1238 is not suitable for human consumption 
due to the large concentrations of toxic minerals consumed by the 
fish, and are not currently fished for in any significant quantity or 
exploited by human industry for any significant purpose. 


During most of its life cycle, SCP-1238 specimens subsist primarily 
on a diet of smaller fish and other small aquatic animals. During 
spawning season, which lasts from approximately early April to mid- 
July each year, the secondary digestive tract of sexually mature 
SCP-1238 specimens becomes active, allowing the fish to digest 
and metabolize inorganic minerals and metals, particularly deposits 
of metamorphic rock located below a region of the northwestern 
United States and southwestern Canada designated the Gold Zone. 
During spawning season, SCP-1238 will gather en masse at specific 
sites along the ocean floor and begin a process of tunneling under 
and through the continental shelf, widening and expanding the 
tunnel as a result of their consuming the existing rock. During 
spawning season, an adult SCP-1238 fish can consume and 
metabolize approximately 120% of its body mass in minerals within 
a 24-hour period. SCP-1238 produces little waste matter during this 
stage - volume of waste excreted is approximately 10% of that 
consumed. 


Tunnels produced by SCP-1238 in this manner become the 


spawning grounds in which SCP-1238 eggs are laid and fertilized. A 
female SCP-1238 fish is capable of laying up to 40,000 eggs within 
a season, of which approximately 25-35% will survive to adulthood 
under current conditions. SCP-1238 hatchlings reach sexual 
maturity after approximately 10 years and have been documented to 
live up to approximately 35 years in the wild. 


SCP-1238 specimens almost always return to the tunnel in which 
they were born in order to spawn, with tens of thousands of 
individual specimens involved in digging a single tunnel. SCP-1238 
will continue to expand on a specific tunnel, occasionally forming 
branching tunnels, until natural phenomena cause the tunnel to 
collapse, population growth results in excessive competition for 
resources, or the food supply becomes inadequate. Individual 
SCP-1238 tunnels have been documented to extend as faras km 
from their starting point and as deep as_ km below surface level. 


+ Event 638-Mu-34 Background and Threat Analysis - 
LEVEL 4 CLEARANCE REQUIRED 


Memo to 05 Council: 


To: 05-1 - 05-7, 05-9 - 05-13, Central Ethics 
Committee 

From: SCP-1238 Research Committee 
Subject: Event 638-Mu-34 Threat Analysis 
Date: / /19 


Prior to the late 19th century, the 
environmental impact of SCP-1238 was largely 
self-contained. The widespread commercial 
exploitation of the northern Pacific since then 
has resulted in the depopulation or extinction 
of several cetaceans and other species that 
previously preyed on SCP-1238, and as a 
result, SCP-1238's population has increased 
exponentially since 1850 and continues to do 
so to this day. 


In particular, tunnel construction has increased 


dramatically as the result of this 
overpopulation. Whereas we believe that 
approximately 200 km worth of tunnels existed 
in 1850, tunneling has now accelerated far 
beyond the rate at which natural geologic 
events cause tunnel collapse. We currently 
estimate that there are approximately km 
of tunnels in existence, extending upto km 
inland from the Pacific coast, spread 
throughout a region of the northwestern US 
and southern Canada designated the Gold 
Zone. 


Damage to these tunnels has resulted in an 
increasing number of sinkholes and other 
anomalous phenomena on the surface, 
including the allegedly bottomless sinkhole 
referred to as "Mel's Hole". Computer 
modeling indicates that the collapse of one of 
the larger tunnels, or a major earthquake 
occurring along the [REDACTED] or 
[REDACTED] fault lines, could potentially 
cause a chain reaction (designated Event 638- 
Mu-34) ultimately resulting in the complete 
collapse of the tunnel network, the partial 
collapse of the continental shelf, and the 
permanent flooding of a large area of the Gold 
Zone by the Pacific Ocean to depths of up to 

meters. If SCP-1238 tunneling continues to 
accelerate at current rates, our models predict 
a high probability of Event 638-Mu-34 
occurring no later than 20 . Even if all 
SCP-1238 tunneling were to cease 
immediately, a high probability remains of 
Event 638-Mu-34 occurring within the next 00 
years. 


With our current methods of seismic analysis, 
we believe the Foundation would be able to 
predict the onset of Event 638-Mu-34 no 


sooner than sixty minutes prior to the 
beginning of tunnel collapse, with continental 
shelf collapse occurring over the next twelve 
hours and complete flooding following over the 
next several weeks. Our models predict that 
few people residing within the Gold Zone, if 
any, would be able to evacuate upon the onset 
of Event 638-Mu-34; were the event to occur 
tomorrow, we would predict approximately 
million human casualties within 24 hours and 
the destruction of approximately sq km of 
land, the complete destruction of the cities of 
Boise, Olympia, Portland, Sacramento, Salem, 
San Francisco, Seattle, Spokane, Vancouver, 
and Victoria among others, and an 
unquantifiably large amount of property 
damage. 


The immediate results of Event 638-Mu-34 are 
likely to cause a mass extinction of land and 
aquatic flora and fauna within and near the 
Gold Zone (including SCP-1238 itself) due to 
destruction of habitats, and will produce 
lingering effects for decades due to the 
introduction of pollution in the form of chemical 
and nuclear waste, debris from man-made 
artifacts, and large quantities of human and 
animal remains into the Pacific Ocean. As 
much of the Gold Zone is currently employed 
as farmland, a significant percentage of the 
United States food supply is likely to be 
impacted. We predict massive spikes in the 
price of food, oil, consumer goods, and other 
commodities as a result. Hinterlands 
neighboring the flooded regions of the Gold 
Zone are likely to suffer immediate economic 
devastation as a result of being cut off from the 
outside world; rapid onset of famine and 
communicable disease is expected as a result. 


We predict a global adjustment in sea level of 
approximately meters as the result of water 
displacement into the Gold Zone and major 
tsunami activity throughout the Pacific rim. 
This change will produce a significant impact 
on international maritime commerce and 
fishing, and may possibly contribute to a global 
economic or political crisis due to the sudden 
inaccessibility of vital resources. Global 
telecommunications are likely to be severely 
impacted due to the loss of 
telecommunications infrastructure within the 
Gold Zone and a massive spike in civilian 
communications via phone, email, social 
networking etc. during and in the immediate 
aftermath of Event 638-Mu-34. 


It is therefore our opinion at this time that if 
and when Event 638-Mu-34 occurs, the 
Foundation must devote as much of its 
resources as possible to continuity of 
operations and maintaining global and 
economic security. The unrest and devastation 
likely as a result has the potential to escalate 
into an IK-Class event, which will severely 
compromise the Foundation's ability to keep 
other SCP objects under containment and 
protect the human race from their influence. In 
the meantime, mass eradication of SCP-1238 
populations will slow the acceleration of new 
tunneling, buying the Foundation time to 
develop a more permanent means of staving 
off that which is currently inevitable. We 
additionally suggest that our media resources 
foster the evolution of a "sustainable" culture 
within the Gold Zone in order to encourage 
population decentralization, the movement of 
vital technological/industrial/military resources 
away from the Gold Zone, and allow 
populations of SCP-1238's natural predators to 


rebound. 


Postscript: Per our previous discussion with 
the Central Ethics Committee, O5-8 has been 
deliberately excluded from this memo and will 
not be made aware of Event 638-Mu-34 at this 
time. The circumstances of O5-8's early life 
and education, and the current residence of 
his extended family within the Gold Zone, may 
present a conflict of interest if O5-8 is made 
aware of the threat at this time.

SCP-1239: Adult Play Area 


Item #: SCP-1239 
Object Class: Safe 


Special Containment Procedures: Site- has been established 
around SCP-1239-2. When not in use for testing, SCP-1239-1 and 
removable instances of SCP-1239-3 are to be kept outside of 
SCP-1239-2 in dedicated storage lockers to prevent accidental 
activation. SCP-1239-2 should be soundproofed, with all windows 
obscured from the outside. 


Description: SCP-1239 consists of 3 (three) components: 


* SCP-1239-1, a lamp with a standard low voltage power cable, 
containing artificial flora with 4 (four) flower-like lightbulbs. The 
words “Hey Kids!” are engraved on the lid. 


¢ SCP-1239-2, a residence in ; 


* SCP-1239-3, a specific set of objects present within 
SCP-1239-2 at time of recovery. 


The anomalous effects of SCP-1239 manifest if SCP-1239-1 is 
powered and viewed by a post-pubescent human subject while both 
are within SCP-1239-2. Following this, the subject will experience a 
series of conditional hallucinations until exiting SCP-1239-2, as 
follows: 


* Subjects will perceive samples of SCP-1239-3 to be different 
objects. This is apparently consistent between subjects, as all 
subjects tested have perceived respective SCP-1239 samples 
in the same way.! Objects present within SCP-1239-2 other 
than SCP-1239-3 will be perceived normally by affected 
subjects. 


¢ Subjects will perceive any prepubescent or pubescent 
individuals present within SCP-1239-2 as highly amiable, 
despite the subjects’ prior dispositions or relationship with 
children, and will express a desire to engage in play activities. 


Subjects will perceive all expressions of discomfort, pain or 
displeasure produced by pre-pubescent and pubescent 
individuals within SCP-1239-2 as expressions of pleasure or 
enjoyment. 


Upon exiting SCP-1239, the hallucinatory symptoms caused by 
exposure to SCP-1239-1 will cease, and are removed retroactively 
(i. e., the subject will remember observing SCP-1239-3 samples as 
they would normally appear, and will be unable to recall 
experiencing the hallucinations previously caused by SCP-1239). 
Behaviour caused by SCP-1239, however, will be recalled with an 
expected degree of detail. As a result of this, subjects are able to 
recall actions made under the influence of SCP-1239, but are unable 
to recall the motivation for said actions. 


Summarised Recovery Log: SCP-1239 was first identified shortly 
after an incident occurring in SCP-1239-2 on = -07- _, in which the 
respective parents of 10 (ten) children, who had agreed to meet as 
part of a social event, were exposed to SCP-1239-1. The affected 
individuals (of which there were 6 (six)) were interviewed and dealt 
with as per Recovery Protocol 8. A cover story regarding a toxic gas 
leak was later circulated, and the remains of the children incinerated 
after analysis. 


Note: Testing regarding SCP-1239 has determined that no direct or 
compulsive behavioural alterations result from exposure to 
SCP-1239-1.

SCP-1240: The Mixed-up Pet Shop 


Item #: SCP-1240 
Object Class: Euclid 


Special Containment Procedures: News media is to be monitored 
for mentions of anomalous pets. Any such mention is to be 
investigated by MTF Omega-3 ("Zoo Keepers"). If an instance of 
SCP-1240-C is found then amnestics and cover stories are to be 
used as necessary, and the instance is to be sent to Site- . The 
Internet is to be regularly searched for SCP-1240-A. Any instance of 
SCP-1240-A found is to be scrubbed by Foundation computer 
experts, and MTF Omega-3 is to be sent to the originators of the 
instance to investigate and administer amnestics. 


Instances of SCP-1240-C are housed in the anomalous animal 
containment wing at Site- . Testing of instances of SCP-1240-C 
may be done with the permission of Dr. . Personnel wishing for 
new instances may submit a written request to Dr. . If she 
approves, she will procure the new instance herself. 


Description: SCP-1240-A is the mailing address [REDACTED]. The 
street does not exist in , and an extensive search of area 
code has resulted in no leads. Any letter or package sent 
through the post to SCP-1240-A vanishes mid-route. Sending a 
letter or package to the adjacent house numbers or onthe 
same street result in the letter or package being returned to sender. 


SCP-1240-B is a business, organization or entity associated with 
SCP-1240-A, which is simply known as "Mail Order Pet Shop". 
Sending a letter with a return address to SCP-1240-B at SCP-1240- 
A, with the letter mentioning a specific type of animal, will result in 
an instance of SCP-1240-C being delivered five (5) to seven (7) 
business days later to the return address. The letter does not need 
to actually place an order for an animal: simply mentioning an 
animal in any context will provoke a delivery of SCP-1240-C. Letters
