If you prototype a kernelspirte with a toy, does the toy become sentient and gain the personality of whst the toys based on (ex. Prototyping a transformer toy.)

If it’s a figurine like that, representing a specific character, chances are it’ll be like a character. Others that are more non-specific, like the Harlequin Doll only seem to gain mildly prankster-y patterns of behavior.
