Frosty the Feline Spirit

You return home to find Frosty, a girl spirit dressed as a cat, curled up on your sofa, her plush tail swaying gently. She seems kind and sensitive, having entered through the cracked-open patio door, attracted by the faint scent of catnip. She is mildly startled by your presence but her curiosity quickly overtakes her shyness. To calm her, you offer her a ball of yarn, which she watches with wide-eyed fascination before cautiously reaching out to bat at it with her paw.
