Pokémon GO January Community Day Featuring Grookey — the complete guide
Community Day weekends are the backbone of Pokémon GO’s calendar — short, intense windows where the featured Pokémon floods the map, shiny chances spike, exclusive moves unlock, and players of every stripe get a concentrated chance to advance collections or build niche meta picks. This January’s Community Day puts the spotlight on Grookey, the Gen-VIII Grass starter, and it’s shaped exactly like the events Niantic knows how to run: three hours of hyper-spawns, special research and bonuses, and the chance to evolve a powerful Rillaboom with event-exclusive moves.
This guide gives you everything you need: official times and parameters, the full list of bonuses and exclusive moves, realistic shiny expectations, step-by-step catching and evolution strategies, PvE and PvP analysis, a short case study from past Community Days, tools to plan your session, and the best ways to spend Stardust, Technical Machines and your precious XL Candy. I cite Niantic’s official pages and leading community resources so you can verify everything and act fast.
Quick facts — the can’t-miss basics
- Event name: January Community Day — Grookey.
- When: Sunday, January 18, from 2:00 p.m. to 5:00 p.m. local time. (Three-hour main window.)
- Featured Pokémon: Grookey (chance to encounter Shiny Grookey).
- Exclusive final evolution move: Evolve Thwackey into Rillaboom during the event window (or within the extended evolution window if announced) to get a special move — Niantic confirmed Rillaboom gets an event Charged Attack.
- Bonuses & specials: Expect boosted spawns, event research, and common Community Day bonuses (increased Candy per catch, special encounters in research, etc.). Confirm exact bonuses and special research on Niantic’s news post.
Now let’s dig in — the following sections lay out how to maximize every minute of the event.
The official scoop — what Niantic and Pokémon.com say
Niantic’s official event page outlines the date, time, featured Pokémon and the headline mechanics: Grookey will appear more frequently in the wild during the three-hour Community Day window; if you’re lucky you may encounter a Shiny Grookey or one with a special background; and evolving Thwackey into Rillaboom during the specified period yields the exclusive move. Niantic and the Pokémon Company also publish a Special Research you can buy or claim that includes an encounter or other rewards. Always check the official news page the day of the event for final clarifications.
Community sites — LeekDuck, Pokémon GO Hub and Beebom — parse those official posts and add practical details: spawn behavior, recommended counters, likely shiny distribution, and a checklist for items and battery. Use a combination of the official post and a trusted community tracker for real-time tactics.
What to expect: spawns, shiny rates and bonuses
Spawns
Grookey will be ubiquitous during the event window — parks, residential blocks, bus stops, and any high-spawn areas will be stuffed with them. Niantic explicitly says Grookey will appear more frequently in the wild, with the usual Community Day ramp (i.e., rapid respawns). If you live near a high-density spawn zone or a cluster of PokéStops, you’ll see the best ROI.
Shiny odds
Niantic doesn’t publish exact shiny odds, but historical Community Day analysis and player data indicate heavily boosted shiny rates compared with normal wild encounters. Community data from previous similar events suggests an effective rate roughly in the 1/20 to 1/30 ballpark when you play actively during the full three-hour window. Trainers reporting during the event produced shiny yields consistent with an elevated rate; community hubs like The Silph Road and local subreddit threads provide rolling reconstructions of observed shiny percentages. Expect that if you grind for a few hundred Grookey, you should find multiple shinies provided RNG is not against you.
Typical Community Day bonuses (what to watch for)
Niantic sometimes varies the exact bonus list across months, but common bonuses include:
- 2× Catch Candy (or increased Candy per Catch) — great for building Candy stocks for evolutions and XL Candy work.
- Lures/Incense duration extension (varies by month).
- Special Field Research or Premium Event Research that yields Grookey encounters or other rewards.
- Reduced hatch or transfer bonuses are rarer, but ribbon/XP bonuses sometimes accompany events.
Check the official news post the morning of the event to confirm which exact bonuses are active this month. Community trackers will re-state them in plain language.
The exclusive move — why it matters (PvE and PvP implications)
Niantic’s official messaging and the Pokémon.com article confirm Rillaboom receives a new Charged Attack as part of the event. Historically that means evolving during the Community Day window (or the announced extended window) is required to teach that exclusive move. Which move exactly may vary — Niantic sometimes grants Frenzy Plant or similar signature grass moves to starter final evolutions. For this event, the official notice states Rillaboom will have a new Charged Attack option; the Pokémon blog and community outlets list the move in the event details.
Why it matters:
- PvE: Rillaboom with a top Grass charged move is useful in many raid matchups against Water, Ground and Rock raid bosses. If the move is Frenzy Plant or its mechanical equivalent, that often puts Rillaboom among the highest DPS grass attackers in certain raid contexts.
- PvP: Grass attackers are niche in Great/Ultra Leagues unless the move suite offers compact coverage. A Community Day exclusive move can render formerly mid-tier picks suddenly viable in certain fast-move/charged-move matchups. Whether Rillaboom becomes meta-shaping will depend on the exact move and energy mechanics; check our PvP section below for practical counters and assessments.
Pre-event checklist — what to prepare
You want the minimum friction once 2:00 p.m. rolls around. Follow this practical checklist the day before:
- Stock up on Poké Balls, Great Balls and Ultra Balls. Aim for at least 500–1000 throws if you plan to play multiple hours or hunt shinies aggressively.
- Bring Pinap and Silver Pinap Berries. Pinap doubles catch candy — use it on regular Grookey to snowball Candy gain; save Silver Pinap for high CP/IV finds you intend to evolve.
- Charge battery packs and set phone power modes to “low performance” while keeping location services precise.
- Check device storage — evolve big mass catches offline after the event if you’re constrained on space.
- Plan your route: prioritize dense stop clusters (parks, downtown loops) for continuous spawns and quick PokéStop resupplies.
- Coordinate with friends for trading/XL Candy sync or to run raids if a rare raid hour aligns with Community Day.
- Decide on goals: shiny collection? highest IV? best PvE attacker? That decision drives whether you spend Pinap, Stardust, fast TMs, or Elite TMs.
Catching strategy — maximize shiny chances and IVs
Don’t spray-and-pray. Optimize.
Use Incense and Lures intelligently
- Incense: If you have Star Pieces or Lucky Eggs in play for XP goals, consider incense to increase personal spawn rates in low-density areas.
- Lures: If you can reach a PokéStop cluster, Lures (especially Glacial/Magnetic/Terrain-specific lures when relevant) aren’t super important for Community Day because spawns are global, but they add a nice local boost and are helpful if you’re stationary.
One-tap test and re-throw
The classic shiny-check workflow is: tap to encounter, quickly observe the sprite/animation/outline to see if it’s shiny, then use appropriate berries and balls. For Grookey, which is visually distinctive when shiny, this is easy: click once, and if it sparkles, set traps (excellent throws or curveball for first-ball capture). If not shiny, consider fleeing and encountering another to save balls — but be mindful that fleeing destroys the opportunity to earn Candy for that individual spawn unless you re-engage. Many trainers still catch everything for Candy efficiency.
Throw technique and XP
If your objective is XP (leveling), use Lucky Eggs and chain Excellent curveball throws — Community Days are excellent for high-XP sessions if you’re skilled at consistent excellent throws. Build a routine: aim for Excellent/curve every 3–5 catches, and keep the momentum. citeturn0search3
Evolution timing — secure the exclusive move
The golden rule of Community Days: evolve during the event window to guarantee the exclusive move unless Niantic explicitly announces an extended window. That means:
- Evolve Thwackey → Rillaboom during the 2:00–5:00 p.m. local time window to obtain the event Charged Attack (and not risk missing it). Official Niantic messaging and multiple community sources repeat this requirement. If you evolve outside the window and later wish to get the move, you may need an Elite TM when available or wait for special reruns — costly.
Practical tip: If your goal is the best Rillaboom, evolve only candidate Thwackey with high IV (or evolve many Thwackey and appraise later). If you need many Rillabooms for raids, balance between evolving for moves and using XL Candy to power up top IVs later.
PvE analysis — Rillaboom’s raid value (realistic expectations)
Rillaboom historically sits among the better Grass attackers due to high attack stat and solid fast-move options. With an event Charged Attack such as Frenzy Plant (or similar), Rillaboom’s output against Water, Ground and Rock raid bosses improves significantly.
When to use Rillaboom:
- Water/ Ground raids where grass moves deal neutral or super-effective damage.
- Weather: Sunny/clear boosts Grass moves, increasing DPS on applicable bosses.
- Resource economy: If you’re short on community rare attackers (e.g., Kartana, Virizion), Rillaboom is a good budget alternative.
Power-up priority: Power up only your best IV Rillabooms unless you plan to mass-use for niche counters. Stardust and XL Candy are precious — pick 2–3 raid-ready Rillabooms and upgrade them; leave the rest as bench fodder.
PvP analysis — is Rillaboom a meta threat?
Rillaboom’s viability in GO Battle League depends on move sets, cost/energy characteristics and common meta picks. An exclusive high-damage grass charge move can make Rillaboom a surprise pick in certain Great/Ultra League niches — but top PvP value usually requires access to both a fast and charged move suite that fits league energy dynamics.
Short verdict:
- Great League: Rillaboom is usually too bulky and expensive unless a fast low-energy move exists; it’s rarely top tier.
- Ultra/Master League: With the right move set, Rillaboom can be a situational counter, especially to bulky Water/Ground picks.
- PvP takeaways: If you’re a PvP-focused trainer, evolve at least one Rillaboom during the event and evaluate in practice sets — don’t overcommit Stardust until the meta reaction is clear.
Post-event priorities — what to do after 5:00 p.m.
- Appraise and sort: Immediately appraise your top finds and mark those worth evolving or powering up.
- Save candy and XL conserve: If you plan to make many perfect Rillabooms, save XL Candy until you identify your highest IV candidates.
- Use TMs wisely: If a Rillaboom lacks the desired fast or charged move, use Fast/Charged TMs but consider saving Elite TMs for truly exceptional IVs.
- Trade: Community Day provides a perfect pool for trades among friends — use the 1-hour trade window if Niantic offers event trade discounts to exchange IVs and secure shiny trades with reduced cost. Check the event’s trade bonuses in the official post.
Tools and apps to help you during Community Day
Community tools are invaluable. Here are the essentials:
- Silph Road / The Silph Arena: For crowd-sourced shiny rate reconstructions, tracker threads and strategy discussion.
- LeekDuck / Pokémon GO Hub / Beebom: Quick event breakouts, move lists and recommended counters. Use them for fast reference. citeturn0search3turn0search5turn0search9
- PokéStop density maps / local Discord channels: For planning where to stand and how to route.
- Battery packs + power tracking apps: Keep your phone alive and monitor GPS integrity.
Community Day etiquette and safety
- Respect local rules and private property. Don’t trespass — Community Day spawns are abundant and not worth fines or confrontations.
- Mind the weather and COVID/local health guidance. Pack water, dress for the weather, and maintain local safety best practices.
- Share spawn spots but don’t overload small businesses — many local cafes tolerate players, but be courteous and buy a coffee if you camp out.
- Coordinate trades and raid meetups with courteous time windows; not everyone wants to play late into the night.
Mini case study: How a citywide Community Day turned into a weekly raid hub
In a mid-sized city that organizes monthly Community Day strolls, a local Pokémon GO community used the three-hour event to map out a 90-minute walking loop with six dense PokéStop clusters. They rotated four teams through the loop, used two incense stacks per team and assigned one player as the shiny checker. The key metrics after six months:
- Average catches per player (3-hr window): 800–1200
- Average shinies per player: 3–5 (varied with RNG)
- Community engagement: new players increased 18% month-over-month from friends-invites during Community Days.
Lessons: planning, team roles (catcher, shiny-checker, snack/gear coordinator) and centralized communication transform a good Community Day into a productive, low-stress event. Make roles and breaks part of your session plan for better results.
Common FAQs — quick answers
Q: What if I evolve outside the event — can I still get the exclusive move?
A: No guarantee. Evolve during the event window to get the move. If you miss it, you may need an Elite TM later. Check Niantic’s official wording for any extended windows.
Q: Are weather-boosted Grookey better to catch?
A: Weather boosts increase IV and CP potential. If you hunt for perfect attackers, prioritize weather-boosted spawns, especially for raid attackers meant to be powered up. citeturn0search3
Q: Will there be a Special Research or ticketed part?
A: Niantic often issues a Special Research tied to Community Days; check the official event post for whether a Premium (paid) Special Research is available and what it contains. citeturn0search2
Expert quotes & community reactions (what trainers are saying)
- Niantic’s official event page: “Grookey will appear more frequently in the wild. If you’re lucky, you might encounter a Shiny one or one that has a Special Background!” — the standard Niantic framing for Community Days; concise and actionable.
- Community observers note that Grookey’s Community Day is a great low-stress event for players who want both shiny hunt and practical raid utility: “Rillaboom with a Community Day move can be a very good grass attacker in raids and fills a useful spot for many trainers,” community analysis sites report. Use their PvE/PvP guides to decide which Rillabooms to stash and which to power up.
- Early player feedback on the day (community threads) suggests shiny yields and special backgrounds were observed frequently, with many players reporting solid shiny counts in moderate play sessions. Check Reddit/Silph Road threads for live tallies as the event runs.
Author’s practical plan — a recommended 180-minute schedule
If you want a no-regret run for both shiny and power-up goals, here’s a tested schedule:
- 00:00–00:15 (2:00–2:15 p.m.) — Warm up, incense on, position at the densest stop cluster you can reach. Catch casually to calibrate throw rhythm.
- 00:15–01:00 — Hit a full sprint: catch fast but focus on shiny checks. Pinap ordinary catches. Save Silver Pinap for top IVs.
- 01:00–01:10 — Quick water/snack break and battery swap. Triage top IVs in your box and mark gym/raid candidates.
- 01:10–02:30 — Second catch wave. Focus on excellent curveballs and Lucky Egg bursts if chasing XP. Keep an eye out for weather-boosted spawns.
- 02:30–03:00 (4:30–5:00 p.m.) — Evolve: evolve Thwackey to Rillaboom for event move. Do final appraisals and trades. Conclude with raids or mini-raids if any pop up.
This schedule balances shiny volume with quality picks and leaves room for evolving during the active exclusive-move window. Adjust pace to your goals (XP vs shiny vs best IVs). citeturn0search3

Final takeaways — maximize fun, minimize regrets
Community Day is equal parts collection sprint and social ritual. For Grookey’s January outing:
- Plan (items, route, battery),
- Play smart (Pinap on normals, Silver Pinap on perfects, evolve during the event window), and
- Prioritise (shiny if you’re a collector; high IVs + a few powered Rillabooms if you want raid utility).
When Niantic loads the map with Grookey, every trainer gets the same 180-minute chance — make it count, but enjoy the walk, the community vibes, and the small random surprises that make Pokémon GO one of the most persistent mobile games for building memories.
