I do not remember a lot about this movie but it has stuck with me.
A little boy got a gift from the moon or some kind of moon goddess.
He got a talking donkey and two stallions and riches.
His brothers stole the horses and riches and went to to town.
The movie ends with the little boy possibly marrying a princess.
It was in the mid to late 80's.
Any help at all would be so very much appreciated!!
