A creepy tidbit from Fever Swamp, a swampcrawl module by Luke Gearing:

"These spirits of lost children are desperate for a light to lead them home. Their shadowy forms clamber through the trees, their large, blank faces staring
greedily from above. Once the time is right, they reach down, snatching any
candles, lanterns and oil before hurriedly fleeing. They can be pacified with
sweet treats. They will not try to fight."
