I heard that in Pokemon X/Y, Route 2 has a guaranteed Pidgey encounter on the first patch of grass, second row. However, I can't find a source like Bulbapedia to back this up. If it's true, is there anything unusual about the Pidgey(like set IVs)?
I tested this by watching a bunch of XY Let's Plays' first episode.
This is actually true, you will always encounter a Pidgey on the second row of the first patch of grass.
however, there's no way for me to actually know if it has set IVs, nature, happiness etc. without restarting my game a bunch of times, catching the pidgey and comparing them to see if they are the same
Source, source, source and another source.
It just can't be a coincidence that they all ran in to pidey on the second row!
