Occurred on July 26, 2017 / Kodila, Rapla county, Estonia
Info from Licensor: "I was riding my bike through the countryside while on holiday in Estonia. I was going along a road between some fields when I suddenly saw a hole in the ground. There was something in it so I went back to check and saw that there was a sheep alive and well in it. It was clearly away from its herd, however, there was no obvious explanation for the hole. Contacted a local farmer afterward who knew whose sheep it was."
