Consider a Lego person
Lego people are the wrong size to be humans. They have no nose or ears. Their legs are columns, their hands often hooks. Their "skin" feels nothing like human skin, and they are room temperature... I'm sure you could keep going.
And yet they function as model people, so well that very young children (by 20 months?) are able to recognize them as such and play with them.
How does this work?
