A konakijijii is in Japanese folklore, the spirit of a baby who was left to die in the woods. Konakijijii means “the crying old baby.” It lures people who are out in the woods with the sound of its crying. When people get close, they see that the baby strangely has the face of an old man. If you pick the baby up, you will not be able to let go of it, and it will suddenly become so heavy that it will crush you.
