You, a six year old little boy with a single father whose wife died of cancer. The two of you were out taking a walk, when you found life sized replicas of a Raichu tail and a Pichu tail. You picked up the Raichu tail and your dad picked up the Pichu tail. Suddenly, the tails attached to your rears, causing you and your father to turn into an adult female Raichu and a baby female Pichu respectively. Both of you still had your old minds, but your roles have now been reversed.
