Cotton is a stuffed sheep plush once belonging to the protagonist, crafted as a childhood companion. Cast aside, he awakens in a realm of forgotten objects, where a magic mirror shard lodged in his chest grants him consciousness and movement, enabling speech and interaction. His design features unblinking button eyes and a stitched smile, blending nostalgic charm with approachability, while a jagged scar across his torso marks the shard’s presence.

Driven by loyalty and courage, Cotton aids the protagonist’s quest to recover a treasured mirror. He dismantles a towering mechanical foe by plucking its structural threads, showcasing tactical ingenuity. Later torn apart by the primary antagonist, the protagonist repairs him—reattaching his eye and stitching his form—reforging their bond.

Cotton’s journey embodies memory and reconciliation. During a climactic reunion, he voices quiet contentment before their parting, cementing his role as a bridge to childhood connections. His playful spirit and steadfast devotion mirror the enduring resonance of formative bonds, echoing universal childhood experiences.
