Today I had a strange experience, and I think the only logic conclusion is that Niantic has included Breeding in the game.
I walked by the street when I saw three mon’s in the same place, one on top of the other. I thought it would be funny to throw a ball in this mountain to see which of them will be catched…
And what a surprise when coming out, that I catched a Houndour.
So, I can conclude that breeding a Mankey, a Paras and a Zigzagoon gives you: a Houndour.
(Future investigation has to show if this result is repeatable)
