There’s a lot to celebrate in this Pokémon Scarlet and Pokémon Violet mass outbreak event! After the release of The Hidden Treasure of Area Zero Part 2: The Indigo Disk DLC on Thursday, December 14, 2023, mass outbreaks of Milcery will be appearing throughout the Terarium at Blueberry Academy until Thursday, December 21, 2023, at 23:59 UTC. Shiny Milcery are more likely to appear in these special mass outbreaks, so don’t miss your chance to find one!

Mass outbreaks are a phenomenon in which many of the same species of Pokémon appear in one location. To participate in mass outbreak events, you will need to download the latest Poké Portal News and install the latest update data for your game. This mass outbreak event occurs exclusively in a location that cannot be accessed without The Hidden Treasure of Area Zero.

Enjoy mixing it up with Milcery, Trainers—and good luck searching for a Shiny one!
