Deok and Related CustomsMore information on rice cake.
1) Expelling Evil Spirits: Traditional Korean toilets had two large footstools with a big and deep hole in between. It was shaped such that children sometimes fell into the hole and injured themselves. People believed that the toilet ghost was hungry and wanted a child to eat. When such an incident happened, people brought in an exorcist who performed an exorcism. They also made a special rice cake called dung deok (excrement rice cake) that they shared with neighbours for the purpose of expelling bad luck for the child.
