The first 2 gardener's sons were set out to find the culprit. They both didn't. Then, the third son saw that it was a golden bird and he shot an arrow which didn't kill the bird, but droped a feather.
There was a tree which bore golden apples. The king really adored it. Every night, there was one apple dissapearing from the tree.
The king sent them to find the bird. The 2 sons never came back. The third son, unlike the first and second, didn't try to kill a fox so the fox told him not to go into the rich village but to into the poor one.
The fox asked him to go straight into a castle and to not put the golden bird into golden cage. But the son did, so the bird shouted and woke everyone. He was to die but would be saved only if he brings the golden horse.
The fox scolded him. The fox asked him to go straight into a castle and asked him to put on the old leathern saddle on the horse instead of the golden one. But the son again puts the golden one. The horse cries out loud which wakes all of them up. He was sentenced to die but would be saved only if he bought the princess to him.
The fox said he will still help. 'At midnight go the princess and kiss her she will agree to come with you but will beg to say bye to her parent, but don't let her. The son did let her. But then he again was sentenced to die but would be saved if he dug up the hill. He couldn't so the fox helped him. And the father let princess go with him.
His brothers pushed him and ran away with everything. The fox helped him get out of the river. Then later on he became the king and met the fox. The fox begged him to kill him and so he did. He turned into a man who was the brother of the princess.
The fox said, 'When you go to give the princess, lift the princess up and ride away with the horse and do the same with the bird' The fox advised him not to sit near the banks of the river. He agreed and went to bring his brothers. He forgot and sat at the river.
