Lucky arrived at Phnom Tamao in 1999 as a six-month-old calf after she was found orphaned and alone in the jungle. Sitheng was tasked with her care. Baby elephants need constant attention, and for two years Sitheng never left her side (even to visit his own family). He bottle-fed her every two hours, took her for walks in the forest to explore and learn which leaves to eat, and stayed overnight, sleeping in a hammock beside her.
Now an adult, Lucky shares an enclosure with Chhouk, a young male elephant who lost his foot to a snare as a calf and now wears a prosthetic shoe. The two spend most of the day together. However, this has not diminished her bond with Sitheng, who still accompanies her on her two daily walks in the forest. His first job every morning, before attending to his other responsibilities, is to greet Lucky, lest she become jealous.
