Oshawott will be appearing more frequently in the wild and attracted to Rainy Lure Modules. The Shiny variant of Oshawott can also be encountered. Take a few snapshots for a surprise. When you evolve Dewott into Samurott during, or within two hours after the event, it will learn the Charged Attack Hydro Cannon. The event will also feature a 3× Catch XP, and Incense and Lure Modules activated during the event will last for three hours. You'll be able to get Oshawott-inspired stickers by spinning PokéStops, opening Gifts, and purchasing them from the in-game shop.
A Community Day-exclusive Special Research story, From Scalchops to Seamitars, will be available for purchase at US$1.00 (or the equivalent pricing tier in your local currency). You will also receive a Rainy Lure Module when you purchase this Special Research. A special one-time-purchase Community Day Box will also be made available for 1,280 PokéCoins, featuring 50 Ultra Balls, five Lucky Eggs, five Rainy Lure Modules, and an Elite Fast TM.
Samurott can now also learn the Charged Attack Razor Shell. This attack will be available for Samurott to learn even after the event has concluded.
