Pokémon was my childhood obsession, so I’ve fallen straight into nostalgia on this. Got a new phone and everything. First thing that happened was me finding a Venonat and then I found a lot more of them…
We clearly have a bug problem around here along with housing a super nest of Vulpixes near the park.
I've got loads and loads of Rattatas and Pidgeys here. Sometimes there are a lot of Eevees. I never get tired of finding an Eevee though.
That there's a whole bunch of Rattatas everywhere never surprised me. The Pokedex entry for Rattata in the very first Pokemon title I ever played includes language to the effect that if you see one, there are definitely forty more in the area.
Though on the other hand I have no idea why Eevee, Venonat, and Vulpix are so common.
Just switch the venonats with Weedles and you are here. (Funny side note: cell signal is also rare. Put a 15cp Weedle in the local gym, it stayed there 2 weeks)
