The story of a river in Kogi State, Nigeria, has been a cause of curiosity in several Nigerians for decades. It is said that in this river, there are several robust fishes. But the crazy thing is this, the fishes in the river can never be cooked, no matter how long they're left on fire.
It is also said that any wound inflicted by the fishes can never heal.
The story is usually told by grandmothers and great aunts. No one knows if it's true or false.
