Oshawott Community Day
September 19, 2021 Pokémon GO Community Day. 6-hour event featuring Oshawott. Shiny rate boosted to ~1-in-25 during the event. Samurott learns Hydro Cannon; shiny debut.
The evolved form learned this move during the event window and from Elite Charged TMs after. This is what makes most CDs pull double duty — get the shiny and a hundo with the exclusive move locked in.
Stack each bonus with the relevant multiplier (Lucky Egg for XP, Star Piece for dust, Pinap Berry for candy) for compounded gains.
Shiny Oshawott was boosted to roughly 1-in-25 during this Community Day — the standard CD shiny rate. Most shiny hunters expect ~12 shinies across the 3-hour event.
What was the September 19, 2021 Community Day in Pokémon GO?
The September 19, 2021 Community Day featured Oshawott. The exclusive move was Hydro Cannon — learned by the evolved form during the event window and via Elite Charged TM afterward. Bonuses: 3x catch XP, 3-hr Incense, 3-hr Lure.
How do I get Hydro Cannon on my Oshawott after the event?
Use an Elite Charged TM (or Elite Fast TM if Hydro Cannon is a fast move) on the evolved form. Niantic occasionally re-releases exclusive moves during anniversary events and Community Day recap weekends — the December recap CD is the most reliable second chance.
Can I still get a shiny from this Community Day?
Yes — the shiny form is permanently released after a Community Day. The boosted ~1-in-25 rate only applies during the event, but you can still hunt the standard ~1-in-500 wild rate or use raids / research / eggs after.
When is the next Pokémon GO Community Day?
Niantic announces Community Days about 2-3 weeks ahead. Check the events page for the current month's schedule and announced upcoming dates.
