Item #: SCP-1420
Object Class: Euclid
Special Containment Procedures: Three instances of SCP-1420 are to be contained in individual perforated-steel containers when not being tested. These containers are to be placed in a 4m x 4m x 2.5m reinforced concrete room with a locked iron door. A gas system capable of flooding the containment room with hydrogen when needed is to be kept in good repair. A reinforced plexiglass viewing window is to be installed and checked for damage weekly. At minimum, two armed guards are to be present during a hatching event to respond to instances of SCP-1420-2.
Description: Instances of SCP-1420 are 8 centimeter long, egg-shaped objects composed of fused segments of calcium carbonate and a leathery material characteristic of reptile eggs. On the tip of each object is a small patch of muscle. At approximately 4:00AM every first and second Thursday of the month, the muscle will contract and SCP-1420 will open despite no cracks or seams being visible. The leathery sections will stretch to accommodate the opening. SCP-1420 will close within 3 minutes.
Upon hatching, a small creature (hereby known as SCP-1420-1) with avian and/or reptilian characteristics will be produced by SCP-1420. Instances of SCP-1420-1 normally weigh less than 600 grams, are often malformed, and typically expire shortly after emergence from SCP-1420. Recorded creatures produced by SCP-1420 include:
- An abnormally muscular snake with a clawed prehensile tail and two legs. Expired approximately four minutes after birth. Necropsy deemed cause of death to be lack of circulation.
- An infant domestic chicken. Completely devoid of feathers and lacking eyes or toes. Necropsy revealed that the bone structure was more similar to that of a reptile than an avian.
- A small multi-colored bird that collapsed on the testing table shortly after birth. Showed no signs of life until Researcher Auer entered to retrieve and terminate. Specimen exploded and coated him in a corrosive material. He recovered and returned to duty after one week.
- A feathered and winged lizard capable of flight. Testing showed that it had several highly venomous retractable spines on its wings. Terminated without incident. Necropsy revealed specimens bone structure to be hollow and lightweight.
- A scaled avian creature with a large growth around its neck. It produced a sound that rendered researchers unconscious for eight minutes. Specimen expired during period of unconsciousness. Necropsy deemed cause of death to be bleeding from severed vocal cords.
- [REDACTED] (See Addendum 1420-A)
Testing has shown that instances of SCP-1420-1 are highly sensitive to levels of hydrogen above normal atmospheric amounts and rapidly dissolve when exposed. In reaction to this, a gas system has been installed that can administer hydrogen as needed.
Approximately 12% of all hatching events will result in a new instance of SCP-1420 being produced instead of an instance of SCP-1420-1. These new instances are ejected at approximately 1 meter per second and are identical to the original SCP-1420 they emerged from. They will begin to produce new creatures on the aforementioned schedule. Extra instances of SCP-1420 are to be destroyed as soon as possible.
Addendum 1420-A: On the date of ██/█/████, a feathered snake slightly larger than average was produced (hereby designated SCP-1420-2) and began to grow at a rapid pace until it had become two meters long. Hydrogen was administered, but SCP-1420-2 seemed to be unaffected and survived long enough to break through the glass viewing window. It continued to increase in size and sprout additional limbs, eventually sprouting multiple scaled arms ending in avian beaks. It was eventually subdued and terminated after causing █ deaths. A necropsy revealed the creature to contain ██ instances of SCP-1420 inside a sack in its larynx. Corpse and extra instances of SCP-1420 were incinerated without incident.
Glass viewing window is to be replaced with reinforced plexiglass and instances of SCP-1420 are to be placed inside perforated steel containers.
Site Director █████: In light of this event, I am assigning two armed guards to be present at all hatching events to react to future instances of SCP-1420-2.
