Weird tuber of yam

A farmer at an undisclosed place in Nigeria harvested this big yam tuber from his farmland and decided to upload it on social media due to its strangeness.
The yam tuber has a close likeness with a human leg as it has what looks like the complete toes of a human being.
Despite the size of the yam tuber, some buyers have been reportedly avoiding it despite the giveaway price.
