The Grass-type Pokémon Turtwig will be the star of September‘s Pokémon GO Community Day, and you’ll definitely want to catch as many of these Pokémon as you can during the event! This Community Day event is taking place a bit earlier in the day than in recent months, so make sure you’re ready to go! The event will happen on Sunday, September 15, 2019, from 11:00 a.m. to 2:00 p.m. local time. Turtwig will appear much more frequently in the wild during this time, and if you’re lucky, you might even find a Shiny Turtwig, which means Shiny Grotle and Shiny Torterra will also make their Pokémon GO debuts. If you evolve Grotle (the evolved form of Turtwig) into Torterra during the event or up to one hour afterward, the Torterra will know a move it can’t normally learn. Plus, during the event, Lure Modules will last for three hours—and you’ll earn three times the Stardust for catching Pokémon!
