The Thing That Won't Leave

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: SCP-XXXX must be removed from Site-19 as soon as possible.

Description: SCP-XXXX is a biological entity with avian features resembling an adult Pygoscelis antarctica. DNA testing has found no relation between SCP-XXXX and members of Pygoscelis antarctica. SCP-XXXX is sapient and is fluent in English, though not in other languages. SCP-XXXX has expressed no desire to learn other languages.

SCP-XXXX displays mild entitlement, regularly using the personal effects of Foundation personnel with no regard for the feelings of the personnel. SCP-XXXX does not heed instructions given to it, interpreting them as attempts at humor. As such, it will deliberately disobey instructions, rendering attempts at containment futile.

SCP-XXXX arrived in Site-19 on [REDACTED] and has refused to leave. Though initially thought harmless, SCP-XXXX's attitude towards researchers and Site-19 has been a source of frustration among personnel assigned to it, as it has repeatedly proven disruptive to Foundation staff members as they work. See Addendum.

Despite multiple attempts to expel SCP-XXXX, it has continued to manifest inside SCP-XXXX, in one instance arriving within a day of having been transported to the bottom of the Mariana Trench. It is speculated that SCP-XXXX possesses teleportation abilities, though this has not been observed. Attempts to terminate SCP-XXXX has failed, including having been decapitated and subjected to SCP-2128.
