A recent update to the free-to-play mobile hit, Pokemon GO, will make it more likely for players to encounter the starter Pokemon; Bulbasaur, Charmander and Squirtle and their evolutions during their endeavours.
The Pokemon GO team at Niantic had this to say about the update:
“In addition, from the afternoon of December 30, 2016, through the afternoon of January 8, 2017 (PST), the first partner Pokémon and their Evolutions, originally discovered in the Kanto region, are more likely to be encountered. This means a greater chance to catch Bulbasaur, Ivysaur, and Venusaur, as well as Charmander, Charmeleon, and Charizard, plus Squirtle, Wartortle, and Blastoise! As a way to increase your chance to encounter one of these Pokémon, Lure Modules will also last for 60 minutes instead of 30 minutes.
Get up and go!”
