Pinata Apples, also called Pinova, are a cultivar apple from Washington. A mix of a cross between a Golden Delicious, Cox's Orange Pippin and a Duchess of Oldenburg. Pinata's haven't been around very long - marketing and official growing only started in 2004.

Pinata Apples are on Facebook (I 'like' them now) and there's also a handy youtube video that talks about them:
