The Legend of the Christmas Spider is actually really cute.
A poor woman was living in a small hut with her children. During summer a pine tree started growing out of their dirt floor and the children tended to it so they'd have a Christmas tree in the winter. However, when Christmas came around they couldn't afford decorations, let alone food and went to bed sad and hungry. The next morning when they opened the windows the sun fell on the tree and revealed that a spider had covered it in cobwebs that glittered like gold and silver. When they looked closer they saw that it was REAL gold and silver. From that day on they always had plenty.
