I can't find number four though. All I can find is this one in the same >> state << but probably on a different >> island judging by the colours<<.
Well done, seefit.
When I started collecting these 'balls' for this puzzle I thought there were only three of them, but when I realized there were more, I decided not to demand all the screenshots. The fourth one has the largest search area, I think, but my referance puts it towards the NW point of the main island (not the largest island).
