Rambo is a famous wild bull of Udawalawe National Park who for about two decades has stood behind the electric fence on the reservoir bund along the Thanamalwila road, begging passing vehicles for fruit and sugarcane. He has always respected the fence and never tried to break out; when the roadside was blocked he swam across the reservoir edge to reach it. In 2013 he was found ill with a gunshot wound and recovered after treatment by DWC vet Dr Vijitha Perera. Signboards asking people not to feed him were put up, but feeding continued.
