There was a Glass Mountain on which an apple tree grew. Anyone who picked the apple would be led into a castle where a beautiful princess lived. Many try but fail and get killed in the process. A knight in golden armor tries but could reach only half way.

In his next attempt, an eagle attacks him and he dies. Another young boy tries to go up but is attacked by a wildcat. He kills the wildcat and uses its claws to climb the mountain. When the eagle attacks the boy, he kills the eagle by playing tricks.

He picks the apple and is led to the castle where he marries the princess. All the previous young men, who were killed while trying to go up, turn alive when the dead eagle’s blood falls on them.
