Breeding with Ditto

As many you should have realised by now that I have fallen into a trap called Pokemon...again but since its been so many years since I last played it i approached this game with a new perspective with a much more mature and and insightful view. When you breed a pokemon you can do it in various ways . 1. shack up a male and female of the same pokemon. 2. breed a female and male pokemon of the same egg type *this is called interracial 0_o* 3. breed a ditto with a pokemon of any gender capable of breeding ( it seems in the pokemon world entire species are infertile)

The point of interest is that the pokemon Ditto, who not only looks like a chewed up pink bubble gum but it can mimic form of any object or thing perfectly and in this case the pokemon I'm gonna breed. It was all fine and dandy until I realised something I wouldn't have paid much thought towards a few years ago...I bred a Ditto with a male pikachu.

Now we can be certain this game is not prejudice towards how people or pokemon swing but the question is where the frak did the egg come from?

Such magnificent observation can only be attributed to my growing wisdom and for attending STHS.
