Kyai Pasir and Nyai Pasir decided to cook the egg for breakfast. After having breakfast with the egg, Kyai Pasir went to farm but suddenly he felt hot and itchy. He rolled to the ground and he turned to be a big dragon snake. Nyai Pasir at home felt the same and she went to farm to meet her husband and she turned to be a snake dragon too. As the heat and itch they felt, the kept rolling on the farm land and created a huge cavity. And followed by water that flows from the land and the basin turned to be a lake (telaga), and the both dragon were sunk.
