I had none before (was using hp grass omanyte and 5IV poliwag as parents), and got 2 males and 1 female. I need to trade the non shiny male to the person whom I was doing this breeding for, which leaves me with a breeding pair (female + shiny male) that I'll need to be able to offer hp grass poliwag with a 1/20 chance instead of the 1/40 chance I had before.
If you have two 5IVs which I'm looking for (details in my thread) or a good offer in general, I could breed you one, but I really don't have stock so to say.
