There once was a family who lived in a great big tower. A mighty king, a propper queen, and two kids Hansel and Gretel. All live happily until one fateful day that will change the fate of them all.
So there they were the king, queen, and Hansel and Gretel. All living peacefully until one day. The king and queen saw something shocking that almost made them scream.
The king and queen saw their favorite knight frozen in stone. The queen's face was white with horror and almost fainted. Then they heard something faint. In order to free me from this stone, you have to cover me with your little one´s blood.
The king and queen were horrified by what they heard, but they didn't know what else to do. So they killed their children and used the blood to free sir dancealot.
When they found some magic string they used it to stitch their children's heads back to their bodies and hoped they would wake up again. But when they did their children did not understand so they did any reasonable thing that any child would do.
