Pokémon GO’s Community Day in August will be scheduled on a special weekend, on August 11-12 and featured Eevee.
Eevee will appear in the wild more frequently for three hours each day. Same as before, it will keep 3 hours Lure Modules.
In additional, 3× catch Stardust.
Niantic did not announced for the Shiny Eevee and exclusive move, so let’s wait Niantic for further announcement.
But, it must be a surprise Community Day, maybe… Gen4 is coming.
