Do you mean Pixie Crunch?  If so, according to the notes I wrote in my Gurney's catalog last year, yes, Pixie Crunch needs a pollinator, and will pollinate with Sundance, Gold Rush, and Liberty. 

I know, not what you wanted to hear, but it appears that the only truly self-pollinating common fruit is the sour cherry.  I did some research on pollinators and crown sizes before buying.  As a result, my orchard, set on my backyard of less than 1/8 acre, looks like this:

1.  Gold Rush mini-dwarf apple

2.  Pixie Crunch mini-dwarf apple

3.  Patio nectarine, planted in the ground

4.  Hardy fig

5.  Apricot tree 1 (forgot variety) -  cold hardy

6.  Apricot tree 2 (forgot variety) - cold hardy

7.  Columnar apple

8.  5-variety dwarf cherry (sour Montmorency, sweet - Van, Ranier, Queene Anne, Bing)

9.  Blueberry 1 (forgot variety)

10.  Blueberry 2 (forgot variety)

By my calculations, I think I planned right for the pollinators.  This year will be only the second year for all of these.
