Piplup, Rhyhorn, Abra, Seedot, Weedle, Gastly, Magikarp, Porygon, Charmander, Electabuzz, Magmar, Totodile, Swinub, Treecko, Bagon, Torchic, Slakoth, Mudkip, Ralts, Turtwig, Trapinch, Chimchar Community Day
December 12, 2020 Community Day. 3-hour event featuring 22 species. Shiny rate boosted to ~1-in-25 during the event. 2019-2020 Community Day recap weekend (Dec 12 and Dec 13).
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 Piplup 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.
B-tier exclusive — useful in specific matchups but rarely the absolute best slot. Hold off on Elite-TM use unless you main the species.
Hindsight verdict — based on how the evolved form aged in the meta. For the live tier rankings see the tier list.
Situational exclusive — picks up a few niche matchups. Worth keeping on a hundo for completion but rarely the top Elite-TM priority.
Was the December 12, 2020 Community Day worth it in hindsight?
B-tier exclusive — useful in specific matchups but rarely the absolute best slot. Hold off on Elite-TM use unless you main the species. Shiny Piplup remains a permanent dex addition either way, so any time spent at this CD wasn't wasted.
What was the December 12, 2020 Community Day in-game?
The December 12, 2020 Community Day featured Piplup, Rhyhorn, Abra, Seedot, Weedle, Gastly, Magikarp, Porygon, Charmander, Electabuzz, Magmar, Totodile, Swinub, Treecko, Bagon, Torchic, Slakoth, Mudkip, Ralts, Turtwig, Trapinch, Chimchar. The exclusive move was All 2019-2020 CD moves — learned by the evolved form during the event window and via Elite Charged TM afterward. Bonuses: 2x catch Stardust, 1/2 hatch distance, Elite Charged TM reward.
How do I get All 2019-2020 CD moves on my Piplup after the event?
Use an Elite Charged TM (or Elite Fast TM if All 2019-2020 CD moves 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 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.
