The xeno was a big, black skinned female with no eyes or mouth. She had high-height breasts and a sharp tail. She was holding a picture of her humanoid form, but she wasn't satisfied with it.

As she drank the milk, her body grew larger and stronger until she became a big strong adult girl with no hair or tail.
