This is one fairy tale I'm not familar with but finding the Hello Kitty of my dreams is the only fairy tale I need. I'm a singing skeleton ever since I found her.

A boar lays waste to a country, and two brothers set out to kill it. The younger meets a little man who give hims a spear, and with it, he kills the boar. Carrying the body off, he meets his brother, who had stayed to drink until he felt brave. The older brother lures him in, gives him drink, and learns of the younger brother's adventure. They then set out to deliver the body to the king, but on passing a bridge, the older kills the younger, and buries his body beneath it. He takes the boar himself to the king, and marries the king's daughter.
One day a shepherd sees a bone under the bridge and uses it to make a mouthpiece for a horn, which begins to sing on its own. The shepherd takes this marvel to the king. On hearing the song, which tells the tale of the murder, the king has the younger brother's skeleton dug up. The older brother cannot deny murdering him and is executed.
