A long time ago when the boundary between Pokemon and humans was unclear there was a man in a desert village.
One day while out in the desert the man got a heatstroke and lost consciousness. He was found by an Alpha Lopunny who carried him to her cave.

The Alpha Lopunny had relations with him and then sent him back to the village.

The next day the man went into the desert to fetch some water, but he lost consciousness again and was carried back to the cave by the Alpha Lopunny.

The Alpha Lopunny had relations with him and then sent him back to the village.

A few days later the man was unconscious at the bar  and the man had a dream. In his dream the Alpha Lopunny said to him.

I can't meet you anymore, but I'll send your child. Your child and mine.

The next morning the man was out into the desert again, but before passing out he found a weird looking Buneary passed out on the sand so the man took her to the cave.

The man had relations with the Buneary and fled to the village.

Full of regret, the man went into the pub and drank until he passed out. The bartender took him back to his room.

The bartender had relations with him and then sent him back to the desert.

The Alpha Lopunny intercepted him and had relations with him until he passed out.

When the man woke up the Alpha Lopunny sent him home.

The man went upstairs, got into his bed and then passed away. The man died of dehydration.
