Between this September 1 and next November 1, a new Eevee carrying a wreath will be available in Pokémon Go.
This new variant of the popular multi-evolution Pokémon will be available at research achievement meetings. “ If you’re lucky, maybe you can find a Shiny Eeveee with a wreath of flowers! “, Cries Niantic in the announcement.
??? From September 1, 2019, at 1 p.m. PDT to November 1, 2019, at 1 p.m. PDT, Eevee wearing flower crowns will be available as Research Breakthrough encounters. If you’re lucky, you might encounter a Shiny Eevee with a flower crown! ✨??? https://t.co/Rwu7IalLFh pic.twitter.com/J9a0nMHPOZ— Pokémon GO (@PokemonGoApp) August 30, 2019
Obviously, by evolving to one of these Eevee, its new form will maintain the crown of flowers, so they may have a variant of Jolteon, Vaporeon, Flareon and all the rest.
On the other hand, the afternoon of this September 1 will be the last opportunity to capture Rayquaza , who will not return in any raid or event this year,
