Inspired/collabed by a convo with @perfecttoasts, here are ways a doll might break laws of physics/reality!
Blushing despite not having blood
Clockwork/electric/etc doll simply ignoring the fact that its energy reserves have run out for the day because it still has work to do!
Not leaving footprints in sand/snow/etc, and walking floating above puddles and grass and flowers, because disturbing nature would be rather rude
Effortlessly avoiding bumping into anyone in crowds because, again, bumping into someone is rude!
Asking politely for doors to open for it, and they do, even locked ones, because it asked so so nicely
Not having a shadow so it doesn't get in the light's way. Imagine a doll's insides being filled with light!
Needing to cool its witch's food instead of warm it, so it turns the microwave upside-down, and this somehow works
Always heating or cooling food to the exact temperarure that's desired, regardless of how long the food was heated or cooled, because it simply demands perfection of itself
Effortlessly being cute and gorgeous and badass every day all the time because a doll is built to SERVE 👏💖💅
Being so Other that it only obeys the laws of physics that it's told about—
Sometimes it floats to dust high shelves because no one told it that entities don't just randomly float.
It can see in the dark because it didn't occur to it that it should have eyes that work like human ones and need light to see.
It doesn't have a reflection, until it's told there's supposed to be another one of it in the mirror, after which point there is now a living reflection in the mirror. The doll and its reflection now clean the house (or at least the room with the mirror) twice as fast! How efficient!
It always has exactly what you need in its pockets, regardless of the size of the object. Dolls must always be useful and helpful, after all!
Its witch said it would be theirs FOREVER so it becomes immortal and indestructible
A doll's existence is already quite magical and anomalous, to be fair
