Brazilian Banana Bonanza Barbie.
Interestingly, she was designed by Robert Best for the Bob Mackie collection, unless this is a typo. She's a Gold Label collector doll, and she's quite cute. I saw a real-life version of her at the National Barbie Collectors Convention, and she's pretty impressive.
She's a Barbie Collector direct exclusive, and you can see additional photos on BarbieCollector.com.
