it's the joy of the hunt, Leland;
feeders at my local Walmart are usually pretty fancy looking goldfish (not a goldfish fan myself, so take that with reservations), and i wouldn't be surprised if some koi snuck in.
since the coloration of koi is hardly a static thing, they could get lucky and find one that grows up really nice. (it's really unlikely that that green baby Kurtsy found was really a wild type that was going to stay that way.) well worth a quarantine tank (which they presumably already have anyway) and a little time
of course, they need to have a big enough tank / pond to put the koi -- that's where the $$ come in
