His mother asked him to fetch some water from the well so that she could make him an oat cake. The second son brought a small amount of water from the well in the broken bucket, so only a small cake could be made. He could take all of it with him with his mother curse or take half with her blessing. As it was small he decided to take it all and leave nothing for his mother. He eventually met the same fate as his older brother. The blade of his knife turned rusty and so the youngest brother decided that he would have to go and find them both.

His mother asked him to fetch some water from the well so she could make him an oatcake. The youngest brother mended the bucket first so he could fetch enough water for a large cake. His mother told him he could take the whole cake with her curse or half with her blessing. He decided that he didn't want o leave his mother without, so he only took half of the cake. 

On his way he met with a shepherd, and goatherd and swineherd who told him about the Red Ettin, the Kings daughter, and the monsters. The young man went on his way and came upon an old woman by the side of the road. She asked him if he had anything to eat and he gladly sat down and shared his oatcake with her. In return she gave him a magic wand that could defeat the monsters and the Red Ettin and rescue the Kings daughter. So when he came across the monsters he didn't run away he stood and faced them and used the magic wand to defeat them. He carried on to the castle of the Red Ettin, but before he could rescue the Kings daughter the Red Ettin came and said if he answered a riddle correctly he would let him go. The youngest son answered the riddle, then he took his axe and shopped off all three of the Red Ettin's heads, found the Kings daughter in the tower and rescued her and then took the wand and turned his brother back from stone. The king rewarded the youngest son with his daughters hand in marriage. And in true fairytale fashion they all lived happily ever after!
