where can I find the strawberry pincushion fruits?

[tinkerbellp]

I'm watching a rerun of the survivorman episode where he is in a desert in Arizona and eats those little strawberry pincushion fruits from that cactus and says that they taste like a strawberry and kiwi. Well I really want to find somewhere online or wherever that I can order these, my boyfriend and I really want to try them! So, if you know of anyplace that carries these please let me know!
