In the Brothers Grimm tale “The Singing Bone,” a wild boar is killed at the start of the story.
A king offers a reward to the person who can kill a dangerous wild boar that has been ravaging the countryside. Two brothers undertake the task. The younger brother succeeds after entering the forest with a spear, while the older brother waits near a tavern and later claims the victory.
The older brother murders the younger one and buries him beneath a bridge. Years later, a shepherd finds a bone at the site and has it made into a flute. When played, the bone sings a message identifying the murderer and recalling the slain animal.
The tale is a Grimm example of supernatural justice: the victim’s remains reveal the crime when ordinary witnesses are absent. Its animal is specifically a wild boar, not a wolf or bear.
