April 3rd, 2010. Examples of SCP-4928 in it's most infectious vehicle to date.

Special Containment Procedures: Project "Bitter Yuca" is currently underway, breeding dominant strains of Cassava1 toxic to SCP-4928. In the unlikely event the general population discovers SCP-4928, a UO-Class "First Contact" suppression campaign has been devised.

Description: SCP-4928 is a parasitic alien life-form present in, and responsible for, all modern forms of tapioca.

Historically, the common shrub M. esculenta subspecies flabellifolia possessed thin, barely edible root structures until 4,500 BCE, when a variant strain spontaneously emerged. This new subspecies produced thick, starchy tubers rich in carbohydrates, and quickly become a staple-food for the developing world. These roots also served as an ideal, deliberate infection vehicle for SCP-4928.


March 15th, 2005. Cassava root, laden with dormant colonies of SCP-4928.

SCP-4928 functions similarly to a bacterial colony, expertly mimicking the polysaccharide chains present in plant starch. This level of chemical camouflage is so advanced, in fact, that Foundation scientists have only recently identified it's existence through comparative study. In it's dormancy, SCP-4928 is resistant to extreme temperatures and high-pressure environments - all historical methods of processing cassava starch have left the parasite totally unharmed. In fact, contemporary forms of Tapioca have only enhanced potential colony growth. Tapioca Pearls or "Boba" create multiple opportunities for the parasite to find a latching-point, similar to of egg-cell fertilization. Sweet and milk teas2 provide a high-calorie liquid medium, further increasing growth factors and ease of consumption.

Despite all modern advantages, SCP-4928 has still failed to form a lasting, parasitic relationship with any terrestrial species.

In contrast to it's extreme resilience in dormancy, SCP-4928 is almost benign in active parasitism. When consumed, this organism quickly succumbs to the hosts digestive processes, immune system response, or simple chemical tolerance. Even in common garden snails, growth is halted by the shedding of thin mucus layers. The human digestive system is especially effective at neutralizing the parasite, which only survives an estimated 0.0001% of all cases3. In this rare event, SCP-4928 will, at worst, cause mild stomach ulcers.

Testing has concluded that SCP-4928 functions at an accelerated timescale incompatible with Earth species - it will attempt metastasize it's host so quickly that it "burns out". Even in ideal lab conditions, when given a vast quantities of nutrient-rich slurry, SCP-4928 still expands too quickly to maintain it's own metabolic growth, resulting a self-cannibalistic breakdown before new external nutrients can be processed.

While SCP-4928 has been unobtrusive and undetected in the population for nearly ten thousand years, project "Bitter Starch" is still considered a priority in the rare chance SCP-4928 finally adapts to terrestrial life.

Addendum - 2010/06/10: Concentrated energy emissions were detected from galaxy MACS0647-JD, operating on standard electromagnetic radio frequency. Per standard UO protocol, embedded assets in global listening posts intercepted this transmission, which contained two messages played simultaneously in 6529 terrestrial languages4. Despite the impressive breadth of translation, the syntax of each language was severely garbled. Message as follows, edited for clarity:

General Notice - Creatures of 9009064.
You have failed. You cannot sustain our young. Weep. Burrow. Die without purpose.

Special notice - Dominants of 9009064.
You are monsters. You are full of sharp rocks and boiling acid. Of the ten million life worlds, you are the most disgusting. We are glad we cannot feed from your filth.
You are children of a whore galaxy.


July 15th, 2010. Domestic Cassava, no SCP-4928 detected.

Addendum - 2010/07/02: All global SCP-4928 colonies have died off. The plant itself appears unaffected, continuing to produce large starchy tubers. A small quantity of parasite-laden tapioca pearls have survived this extinction, shielded within Site-45's deep-freeze storage.

Given the potential shelf-life of SCP-4928, this anomaly will be considered neutralized as of June 18th, 2060.

I wrote, and vaulted this story a long time ago. Like most authors on this site, that's not unusual. Ideas come, and go, and a lot never make it to posting. I always regretted not fixing this one up, though. I really liked the dialogue and concept, so I came back to it. This is the first time I've revived a tabled article - I tend to write whatever ideas come to me in the moment.

I hope it works out, and more importantly, I hope you enjoy reading it.

Side-note. This Iris Black isn't intended to mirror the Iris Black in other MC&D articles. She's my interpretation of the character: someone older, and entirely different. Marshall, Carter, and Black are all fantastic characters, but I can never seem to write within the lines of someone elses narrative. That said, I whole heatedly encourage you to explore the MC&D Canon, and the many fantastic articles and tales within.
