The next time the Piper showed up it was June 26, which was Saint John's and Saint Paul's Day. He began to walk through the town, playing his pipe, and all the children came out and followed him. He led them to a place nearby called Koppenberg Mountain, and a cave opened in the hillside. They all went inside, then the opening closed up, and they were never seen again. The only children left in the town were a blind boy, a lame boy, and a deaf boy who had not been able to follow the Piper.
