The Frog Boys (Korean: 개구리소년) were a group of five South Korean boys who disappeared on March 26, 1991. The boys had gone to nearby Mount Waryong to catch frogs but never returned. Their bodies were found 11 years later. Although it was discovered that they had been murdered, the case has never been solved. The incident was the subject of two films, Come Back, Frog Boys (1992) and Children (2011) and several songs.^[2]
