But the original story's are nothing like the disneyland productions.
Sounds like the mummys are just babys who's parents thought they had been replaced by some nefarious entity. One has to just assume its post pardom depression but its weird that these fairys are described as looking like humans.
In August 1909 an old woman of Donegal, Annie McIntire, applied for a pension. She told the Pension Committee that although “she did not know the number of her years,” she “remembered being stolen by the ‘wee people’ (fairies) on Halloween Night, 1839.” Was she certain of this?
“Yes, by good luck my brother happened to be coming home from Carndonagh that night, and heard the fairies singing and saw them dancing round me in the wood at Carrowkeel. He had a book with him, and he threw it in among them. They then ran away.” The applicant added that the people celebrated the event by great feasting and drinking. The committee decided to grant her a pension.
