"Confetti the Clown"

SCP-1313 is a humanoid-ventriloquist dummy entity measuring 1.5 meters in height, presenting a composite clown-mime aesthetic with monochrome coloration and ambiguous gendered features. Distinctive markings include small black stars painted on each cheek. The subject's mouth contains a set of razor-sharp dentition capable of efficiently removing flesh from bone.

SCP-1313 exhibits extreme stealth capabilities when motivated, capable of silent, sustained movement toward designated targets. Aggression is typically preceded by an auditory warning manifesting as the sound of a slowly winding jack-in-the-box, culminating in the melody of "Pop Goes the Weasel." This sound manifests within the perception of the intended target regardless of ambient noise levels or hearing protection.

Behavioral patterns are binary and condition-dependent. When sufficiently fed and provided regular opportunities to perform circus acts, SCP-1313 displays a content, playful demeanor accompanied by childlike vocalizations. Instances of hunger or exposure to specific human pheromonal profiles trigger an immediate transition to a predatory state characterized by silent, deliberate hunting behavior.

Containment is uniquely maintained through the constant presence of a designated personnel profile. A male guard exhibiting gruff, socially isolated ("incel-like") traits must be stationed within a 100-foot radius of SCP-1313's primary containment cell at all times. The mechanism by which this profile inhibits SCP-1313's predatory impulses is not fully understood, but it remains 100% effective to date.
