Lullaby Lemur - SCP-PRIME-004

Containment Procedures:

SCP-PRIME-004 is to be housed in a soundproof containment chamber measuring 5m x 5m, with reinforced walls to prevent escape attempts.

All personnel interacting with SCP-PRIME-004 must wear specialized earplugs capable of blocking its vocal effects.

Interaction is to be limited, and any experiments or tests involving SCP-PRIME-004 must be conducted via remote-operated equipment.

Object Class: Keter

Once SCP-PRIME-004 begins singing, individuals within a 30-meter radius will feel an overwhelming sense of calm, followed by an irresistible urge to sleep. This effect intensifies if the subject tries to resist, causing disorientation, nausea, and eventual unconsciousness.

Victims who fall asleep in SCP-PRIME-004's presence enter a comatose state, during which SCP-PRIME-004 climbs onto their chest and appears to feed off their life energy, rapidly aging them. Autopsies have revealed that victims' internal organs atrophy at an accelerated rate, leading to death by organ failure within 48 hours if untreated.

SCP-PRIME-004 is highly intelligent and has been observed actively seeking out humans, often mimicking sounds of distress or speaking in a childlike voice to draw in potential victims.

Its intelligence makes containment extremely difficult, as SCP-PRIME-004 often uses distractions or feigned innocence to escape containment measures.
