“The Green Children of Woolpit were two children who appeared in the village of Woolpit in Suffolk, UK, in the 12th century. The children were brother and sister and they had green colored skin. Their appearance was normal in all other areas. They spoke an unrecognized language and refused to eat anything other than pitch from bean pods. Eventually their skin lost its green color.
When they learned English they explained that they were from the `Land of St Martin’ which was a dark place because the sun never rose far above the horizon. They claimed that they were tending their father’s herd and followed a river of light when they heard the sounds of bells – finding themselves in Woolpit.
Some of the more unusual theories proposed for the origin of the children are that they were Hollow Earth children, parallel dimension children, or Extraterrestrial children.”
