SCP-725 in an early stage of growth

Item #: SCP-725

Object Class: Euclid

Special Containment Procedures: SCP-725 is to be maintained in stasis at a secure Level 4 Biohazard containment facility at a temperature of 37 degrees Celsius (98.6 degrees Fahrenheit) and 50% humidity. As SCP-725 consumes approximately 1.5 ml (.05 fl. oz.) of nutrient solution every 24 hours, personnel are to ensure that the nutrient level is kept above the marked line. Waste matter should be purged at least once a week according to biohazard protocols.

D-Class Personnel tasked with maintaining the apparatus are to be provided with hazardous materials protection gear, including fully contained respirator gear and full-body coverage isolation suits. Should SCP-725 breach containment, infected personnel are to be terminated on sight by gunfire. SCP-725 is to be removed and returned to its glass container by personnel wearing hazardous materials protection gear. The bodies of any infected host are to be sealed inside Tyvek bodybags, euthanized by lethal injection, and then incinerated with all particulate matter recaptured and sequestrated to prevent contaminants from escaping into the outside world.

Description: SCP-725 is a jacket-shaped mass of tissue with the following composition:

  • 50% embryonic stem cells derived from laboratory mice (Mus musculus domesticus and Mus musculus musculus hybrid)
  • 49% human brain tissue.
  • 1% unknown organic matter, apparently [DATA EXPUNGED]

SCP-725 is both animate and sentient, and although incapable of vocalizing, has been observed making attempts to communicate through gestures. Although the object appears to be capable of percieving vibration and motion within an approximately ten-foot radius, it possesses no other senses and cannot percieve light, odors, or [DATA EXPUNGED], except when [DATA EXPUNGED]. The object responds to human voices (apparently through sensing the vibrations of air molecules).

SCP-725's only danger comes from its ability to capture a human host. Upon skin-to-skin contact, SCP-725 will entangle the host by enveloping the host's upper torso and arms, then insert several probes into the back of the neck, near the brainstem, overriding the host's central nervous system. Two more probes will then tap into the carotid artery, drawing nutrition from the host's bloodstream until depleted.

Addendum: SCP-725 was originally constructed as an exhibit at the New York Museum of Modern Art. Upon discovery of the object's unusual properties, the artist was given a Class B Amnesiac, and the object replaced with an inert duplicate, which was later euthanized by the artist. The original was taken into Foundation custody by three Class-E Personnel, two of whom were subsequently terminated due to [DATA EXPUNGED].

Addendum: It's started growing buds. I think it might be trying to reproduce asexually. Little jackets all over the sleeves. Oh God, they're moving. What if this thing has a mobile polyp phase? Please advise! - Dr. Flynn, Head Researcher.
