This type of tuber is not a normal potato, it is actually a tuber with the scientific name Dioscorea Hispida Dennst, belonging to the Dioscoreaceae family.
This is a poisonous tuber. If not carefully processed and handled, the person who eats it can be poisoned and die. Usually, this root is used to make a medicine in Oriental medicine.
This type of tuber is often confused with potatoes or brown tubers, so there are many cases of people being poisoned by this tuber. However, in reality, it is very rare to see a tuber shaped like a child that this girl accidentally dug up. But anyway, luckily for the girl, someone discovered and stopped her in time.
