A new event was announced today officially revealing Generation 3 Pokemon! It begins tomorrow, October 20th, at 3:00pm EDT.
There will be 5 new Ghost-type Pokemon introduced from Generation 3. Also, shiny sprites of all the new Pokemon in the update have been found, suggesting that the shiny form of all these Pokemon will be available. This is a huge step seeing as we currently only have two families of Pokemon able to be found shiny in the wild. Maybe all Pokemon will be able to be found shiny once Gen 3 is launched.
All these Pokemon have an increased spawn rate as well as Cubone, Drowzee, Gastly, and other spooky Pokemon (full list not available yet).
On top of all that, All Pokemon caught, or used as your buddy will receive double candy during the event.
A new box will also be available in the shop for Raid Passes and Super Incubators.
All Players also recieve a special Mimikyu Hat for free to accompany them on their adventures.
The rest of Generation 3 will be in Pokemon GO before Christmas time. So be looking forward to that!
