Things You Didn't Know About Pokemon: Book II

Fact #317

Mawile is based of the Japanese legend of the Futakuchi-onna. 

The legend goes as follows: 

A cheap man living in a small village has chosen not to find himself a wife simply because he does not want to pay the extra expenses of having one live in the house.

One day, he met a woman who did not eat anything, whom he immediately took as his bride. But, he began to notice how his stores of rice began to slowly decrease in number. 

So, one day, he pretended to leave for work, but in actuality, he stayed behind to spy on his rice and his new wife. To his horror, he saw his wife's hair part on the back of her head, her skull split wide revealing a gaping mouth. She unbound her hair, which reached out like tentacles to grasp the rice and shovel it into the hungry mouth.
