Lucky was busy munching on some freshly cut grass when she spotted a special treat a tourist was holding out. She dropped her next mouthful of greens and extended her trunk, asking for the banana.

“She loves bananas the most, also sugarcane or watermelon,” said Lucky’s caretaker, Aon Salangam. His magnificently intimidating elephant may weigh almost four tons and stand nearly 10 feet tall, but “she is a sweetheart,” assured Mr. Aon.
