Item #: SCP-XXXX
Object Class: Euclid
SCP-XXXX was first discovered by the unaffiliated, and now expired, Dr. ████ █████, from whose research the majority of the information about SCP-XXXX has been compiled and formalized.
Special Containment Procedures: SCP-XXXX is currently being restrained by itself in a mine shaft at 71 meters under the sea level in ███████, Italy and. Its containment site must be held under strict surveillance for geological activities and extreme weather conditions at all times. In the case of nearby seismic activities of magnitude 3.0 or above or threatening weather conditions, a specialized crew located in ████ ██ █████ must be contacted immediately by surveilling guards to keep SCP-XXXX from falling any further down the mine shaft and if possible to secure it for long term containment.
In future containment SCP-XXXX is to be kept in a cage in the very middle of a sealed 20x20x20 meter room pressurized at 1013 mbar, heat controlled to 0.9°C, at local sea level and at a location absent of potential hazards that may change SCP-XXXX's surrounding conditions or location.
Description: SCP-XXXX reacts to surrounding altitude relative to local sea level, atmospheric pressure and temperature. At sea level, under an atmospheric pressure of 1013 mbar as well as at a temperature of 0.9°C SCP-XXXX is in its most stable form: a floating spheroid covered in long soft creases, to quote Dr. █████, similar to spaghetti noodles both in colour and in texture. The actual material of said creases is unknown. Under normal conditions, SCP-XXXX measures roughly 208 cm in diameter and stays suspended above the ground at around 23 cm with lows of 15 cm and highs of 50 cm. Under its creases, SCP-XXXX has three more known layers with varying characteristics. All layers are under normal conditions safe for skin contact, although prolonged effects are unknown and excessive contact is therefore not recommended. Additionally, ingestion of SCP-XXXX is prohibited.
The properties of SCP-XXXX and its layers will henceforth be described in its most stable form unless otherwise specified.
First layer, Stratum Vermis: The first layer is characterized by the aforementioned creases, which converge on opposite sides of SCP-XXXX to form two puckered entrances through which access to the deeper layers is easiest. All material separated from SCP-XXXX's body quickly boils away into whatever mixture of gases it's surrounded by and an amount of gas correspondent to the amount lost is filtered back into SCP-XXXX's body through the Stratum Vermis, which acts like gills. SCP-XXXX seems to perceive its surrounding conditions through its outermost layer, which itself reacts to temperatures. SCP-XXXX will only account for the average temperature of its vicinity up to 10 m around, so any abnormally hot or cold object in contact with the Stratum Vermis will only have notable effects once it warms up or cools down the surroundings to above or under 0.9°C.
Under temperatures under 0.9°C, the Stratum Vermis will start retracting and tightening inside the two openings on opposite sides of SCP-XXXX. This effect seemingly stops at approximately -22°C. In temperatures over 0.9°C, the Stratum Vermis will start expelling its creases from the openings on opposite sides of SCP-XXXX. The loosened creases float in the surrounding air similarly to hair in water. The Loosening of the creases isn't known to stop at any temperature, but is greatly slowed down in temperatures over 23°C. Both reactions to temperatures aren't immediately dangerous but care in the handling of SCP-XXXX during changes in temperature is highly recommended.
Second layer, Stratum Tritus: The second layer is characterized by flowing rivers, pockets and fluctuations in density of the layer's material, described by Dr. █████ as identical to that of a minced meat paste. The Stratum Tritus reacts to altitude explosively. At sea level it constitutes approximately 80% of SCP-XXXX's volume but expands at lower altitudes and contracts at higher ones. The expansion of volume is exponential and isn't known to stop at any altitude. The maximum size of SCP-XXXX ever recorded is at 71 meters below sea level, where it has filled an entire 109 m3 room and exerts a pressure on the surrounding walls and bedrock equivalent to 5700 tons. The minimum size of SCP-XXXX is recorded at 190 cm in diameter at an altitude of 82 meters. When taken from above sea level to below in quick succession the changes in the Stratum tritus' and SCP-XXXX's size are amplified.
The Stratum Tritus' internal fluctuations in density are seemingly random and at most, strong enough to break a human ulna and radius bone. Although pressures high enough to cause critical damage are rare, handling of the second layer of SCP-XXXX must always be done equipped with specialized tools.
Third Layer, Stratum Nubis: The third layer is characterized by a seemingly empty area around SCP-XXXX's core. Further inspection reveals that the Stratum Nubis is a powder-like material with gaseous properties, which reacts explosively when brought outside of SCP-XXXX's body, more so than any other layer.
In an atmospheric pressure above or below 1013 mbar the Stratum Nubis will crystallize into sharp structures similar to that of sugar. Samples of this crystalline form are more stable outside of SCP-XXXX but will explode and shatter within 2 - 7 minutes. In a regular atmosphere of air small amounts of the Stratum Tritum are harmless and will simply cause a loud pop, but when researching larger samples special precautions are required.
Fourth layer, Stratum Atramentum: The fourth layer is characterized by a smooth perfectly round metallic marble-like shape. The Stratum Atramentum's surface coats anything it comes in contact with with a black semi-viscous substance similarly to a ballpoint pen. The "ink" the Stratum Atramentum excretes boils away quickly outside of SCP-XXXX and is seemingly harmless. Unlike the preceding layers, the Stratum Atramentum does not seemingly react to any outside properties.
The Stratum Atramentum is the last known layer of SCP-XXXX. All attempts at breaking through it have failed.

[201 seconds]
Per l'ennesima volta, ho completamenta trascurato ongni precauzione possibile ma questa volta non sò se me la caverò con uno spavento e un braccio rotto … La perdita di questa magnifica creatura e peggio della morte … E poi morire nella stessa miniera che scavai, mado' che cazzata, mi sono letterralmente scavato la tomba [laughter]. Boh, però alla fine non è propio il peggio. Morirò al fianco dell'unica cosa che ebbi mai amato. Chissà che spavento a quelli che mi trovano qui morto sotto una sorta di gigantesca polpetta alinena. Ma … se mi trovate vi prego, non feritela … Non vuole male … E … Se mi state ascoltando sicuramente avrete anche trovato le mie ricerche … Continuate, siate più prudenti di me, non lasciatela cadere. Vi prego.

For the umpteenth time I've ignored any possible safety precautions, but this time I don't think I'll get through this with a scare and a broken arm … The loss of this magnificent creature is worse than death … And also, dying in the very same mine I dug, Jesus, what a joke, I literally dug my own grave [laughter]. Oh well, in the end, this isn't the worst possible outcome. I will die beside the one and only thing I've ever loved. just thinking of the scare whoever finds me will get once they see me dead under some kind of alien meatball. But … if you find me, I beg you, don't hurt her … She doesn't want anything bad … And … if you're listening to me surely you've already found the rest of my research … Continue, be more cautious than me, don't let her fall. I beg you.
