Item #: SCP-3578
Object Class: Euclid
Special Containment Procedures: All SCP-3578 instances are stored in a standard Safe locker outside of testing. SCP-3578-A instances are kept in a specialized dinosaur habitat with adequate vegetation and and electric fence, and are to be monitored by members of MTF Phi-2 ("Clever Girls").
Reports of ceratopsian dinosaurs are to be investigated, and MTF Phi-2 deployed to capture any SCP-3578-A or SCP-3578-B instances present.
SCP-3578-B instances are kept in individual, reinforced dinosaur enclosures, and supplied with a live pig once every two days.
Description: SCP-3578 instances are rubber hand puppets in the shape of a Triceratops head.
When a subject wears SCP-3578, it will adhere to the subject's hand. When attached, SCP-3578 is sentient and behaves as such. The subject can 'feed' SCP-3578 plants by opening and closing their hand to make SCP-3578's mouth open and close.
No compulsive or memetic effects have been identified. If test subjects decline to feed or play with SCP-3578 for several days, SCP-3578 will become inert and detach from the subject's hand until worn by someone new.
If SCP-3578 is continually fed, it will gradually expand to cover more of the subject's body. Additional rubber, dinosaur-shaped accessories will manifest near the subject while they sleep: these include gloves and boots shaped like Triceratops feet, a wearable rubber tail, and a poncho with a reptilian skin pattern.
After 2-3 days, SCP-3578 and any added accessories worn at the time will stretch until they envelop the subject's entire body. At this point, SCP-3578's rubber components will fuse at their junctions and form the shape of a juvenile Triceratops, and peel itself off of the subject. In 2-4 hours, SCP-3578's rubber will transmute into reptilian flesh and SCP-3578 will become a visually nonanomalous Triceratops, designated SCP-3578-A. SCP-3578-A will then proceed to lay a clutch of eggs, each one hatching to reveal a new instance of SCP-3578.
Addendum: D-61195 was instructed to feed his SCP-3578 instance meat in place of plants. SCP-3578 stretched to envelop him after only 12 hours of adhesion, and did not eject D-61195 upon taking form. The resulting dinosaur, designated SCP-3578-B, resembled a stocky, quadrupedal tyrannosaur with a Triceratops frill and horns. Testing revealed the non-ceratopsian features (jaws, teeth, hip bones, and claws) to be a genetic match for D-61195.
