She added: "Suddenly he got spooked and he just ran, ran and ran."
After a sighting on Saturday morning, Clare and Ross rushed to the park and found him "sitting really quietly by the tree trunk".
Pig Beach, or Pig Island, is an uninhabited island in Exuma, the Bahamas, famed for its many swimming pigs.

Okunoshima Island, in Japan, attracts tourists to witness its huge rabbit population that has taken over the island, with many people visiting to feed the animals.

The jungles of Guam have up to 40 times more spiders than the forested areas of the nearby Pacific Islands thanks to the invasive brown snakes that wiped out 10 of the 12 spider-eating bird species. Because the birds ate some of the insects that spiders eat, there is also now more food for the spiders to eat. One of the most common types of spider in the jungle is the yellow and black Banana Spider.
