The Seasons Change: Part 2 - Strange Eggs

Features

• Defeat a Team GO Rocket Leader to receive a Strange Egg, and walk 12 km to hatch it. You’ll need to have space in your Egg inventory before your battle with Sierra, Cliff, or Arlo in order to receive a Strange Egg. Strange Eggs will continue to be available in Pokémon GO after the event ends.
• For the first time since March, new Team GO Rocket Special Research will be available! Join Professor Willow as he and the team leaders investigate Team GO Rocket’s involvement with Strange Eggs, culminating in a battle with Giovanni himself! This is the last Team GO Rocket Special Research in 2020. If you currently have the The Shadowy Threat Grows Special Research from earlier this year, you’ll need to complete it first before you can obtain this new Special Research.
• Take a snapshot for a surprise! (Nidoran♀, Nidoran♂, Vulpix, Oddish, Seedot Encounter)
• Team GO Rocket Leader avatar items are now available in the shop. Perhaps you could use these avatar items to infiltrate and investigate Team GO Rocket! GO forth, Trainer!
• Finally, defeat Giovanni for a chance to rescue Shadow Mewtwo! This is the first time Shadow Mewtwo is available in Pokémon GO outside of the Rocket Straight to Victory Special Research, which was exclusive to Pokémon GO Fest 2020.
• After this event begins on Monday, October 12, 2020, at 1:00 p.m. PDT (GMT −7), you’ll be able to save Shadow Mewtwo and Shadow Pokémon from Giovanni, the Team GO Rocket Leaders, and Grunts when those Team GO Rocket members are piloting Team GO Rocket balloons. However, you won’t be able to encounter the Team GO Rocket Leaders’ new Shadow Pokémon or Shadow Mewtwo from PokéStops until the next day in your local time.
