The Pokemon Go Twitter account has brought great news to fans tired of Rattata, Pidgey and Zubat. The implication is that, most players find pages and pages of these boringly common Pokemon, that will become less likely as rarer, more interesting critters are found instead.
Professor Willow has discovered that you may encounter other Pokémon where Pidgey, Rattata, and Zubat were previously more commonly found.
