The Kiwi breeders of the Melbourne Cup winner say they are thrilled at his success.
And they have also revealed a secret - that Prince of Penzance has a full brother still on the farm who looks just as good.
Rich Hill Stud is a thoroughbred nursery based in Walton, in the Waikato. The farm's managing director, John Thompson, said staff were going crazy after jockey Michelle Payne stormed through first to the finish line on the horse they bred.
"Once we breed them, we honestly follow them with a passion because they're like our children," he said. "We're pretty excited here. I guess, for us, it's the holy grail of breeding. And for one of the horses raised and sold off the farm - it's just put this farm in the world's spotlight. So it's great."
