Nakoruru by Takara had a Jenny body, but her head mold was totally new. Its distinctive features were a round face and a crescent-shaped smile drawn as a thin line.
It was used on some other Takara dolls and then, in 1999, it was borrowed by Azone for their Sahra dolls!
The head was remodelled to fit 60 cm dolls, but the features remained the same.
Now, as far as I know, the mold is out of print and you can see it on vintage dolls only.
