泥田坊
Dorotabō are the transformed ghosts of old men who toiled hard on their rice fields, only to see them lie in waste by neglectful owners after their death. 

They are described as figures of mud rising out of the field, retaining only one eye and three fingers to a hand. The latter is due to a belief that, in life, three fingers are tied to vice and two to virtue, and that as vengeful spirits, only vice remains.
