She's a technically a fakie
While she is made by Estrela, she was made for the Susi doll line, not MLP. She's molded after actual hasbro ponies (Baby Lofty's head and Baby Tiddlywinks' body), but is smaller than regular Brazil babies.
ETA: She was released after the regular MLP line stopped too, I want to say in the 2000's sometime but I'm not entirely sure.
