On a tiny uninhabited island in the Bahamas called Big Majors Spot, there is a group of wild pigs. Nobody knows how they got there some decades ago -- was it a shipwreck? Or somebody setting them out to harvest them later? But there they are, and there's not much food on the island, so locals began boating out there and feeding the pigs.
The smart pigs realized that the sound of motors was the sound of food, and first pig to the food wins... so they learned to swim out to the boats to be the lucky ones. And then they all swam. And after decades of this, they became a tourist attraction.
You can swim with them, but they don't care about you all that much; what they want is the goodies.
Once the food is dispensed, they head right back to dry land.
