Rillaboom Rumbles In: Mastering Grookey Community Day 2026 in Pokémon GO!

Hello, Trainers! Get ready to kick off 2026 with a rhythm and a roar in Pokémon GO! Mark your calendars because the very first Community Day of the year is almost here, starring the energetic Chimp Pokémon, Grookey! Straight from the Galar region, this Grass-type starter is poised to make a significant impact on your roster. Pokémon GO Hub has dropped the essential intel, and we’re here to break down everything you need to know for Grookey Community Day, ensuring you drum up maximum success!

Grookey Community Day is scheduled for **Sunday, January 18, 2026, from 2:00 PM to 5:00 PM Local Time**. This crucial three-hour window is when the magic happens, offering a limited-time opportunity to evolve Thwackey (Grookey’s first evolution) into Rillaboom to learn its exclusive Community Day move. You’ll have an additional four hours after the event ends, until 9:00 PM local time, to secure this special move for your evolved Rillaboom.

### Meet Grookey: The Galar Groove Machine
Grookey, the cheerful Grass-type starter from the Galar region, is renowned for its drumming prowess. Its evolutions, Thwackey and the mighty Rillaboom, amplify this rhythmic theme, culminating in a powerful ape-like Pokémon wielding a tree drum. Rillaboom boasts impressive stats and a unique design, making it a fan favorite. This Community Day is your prime chance to catch an abundance of Grookey, gather enough candy to evolve multiple Thwackey into Rillaboom, and secure a formidable Grass-type attacker for your team. Whether a seasoned Trainer or just returning, Grookey’s cheerful presence will bring some rhythm to your Pokémon GO adventures.

### Rillaboom’s Exclusive Move: A PvE Game-Changer?
A cornerstone of every Community Day is the exclusive move the featured Pokémon’s final evolution learns when evolved during or shortly after the event. While the specific move for Rillaboom hasn’t been explicitly detailed in the initial announcement, history tells us it will be a potent Grass-type attack designed to elevate Rillaboom’s performance. Given the “PvE Guide” highlight, it’s highly anticipated this exclusive move will make Rillaboom a significant contender in Raids and Gym battles. Imagine a Rillaboom unleashing a powerful, optimized Grass-type charge move, capable of dismantling Water, Ground, and Rock-type raid bosses. This exclusive move often transforms a good Pokémon into a great one for specific applications, making it crucial to evolve your best Grookey during the event window.

### Why Grookey Day Matters for Your Battle Roster
For Trainers focused on Player versus Environment (PvE) battles – Raids and Gyms – Grookey Community Day presents a golden opportunity. Rillaboom, with its solid attack and bulk, combined with a potentially game-changing exclusive Grass-type move, could become a top-tier Grass attacker. Grass-types are invaluable against numerous common raid bosses, including legendary Water-types like Kyogre, Ground-types such as Groudon, and Rock-types like Terrakion. A team of high IV, maxed-out Rillaboom with its special move can significantly reduce raid clear times, allowing you to short-man raids for more rewards and experience. Even if not the strongest, its accessibility makes it an excellent budget option or a solid addition to any trainer’s lineup.

### Community Day Perks: Beyond the Pokémon!
Beyond the Grookey bonanza, Community Days are celebrated for their generous in-game bonuses. While specific bonuses often mirror past events, you can typically expect:

* **Increased Shiny Odds:** Significantly higher chance to encounter a vibrant shiny Grookey.
* **Boosted Stardust/XP/Candy:** Enjoy increased Stardust, XP, or Candy – activate a Star Piece or Lucky Egg!
* **Extended Lure Modules & Incense:** Both often last for three hours, drawing more Pokémon.
* **Special Trades & Trade Discount:** Bonus special trades and Stardust cost reduction for swapping high IV Grookey or shinies.
* **Surprise Snapshots:** Take snapshots for a chance at a surprise Grookey encounter!

These bonuses amplify your gains, making the three-hour event incredibly productive. Plan to maximize these perks, especially if low on Stardust or keen to level up quickly.

### Gear Up: Your Pre-Event Checklist
To ensure you make the most of Grookey Community Day, a little preparation goes a long way:

* **Poké Balls & Berries:** Stock up on Great and Ultra Balls, plus Pinap Berries.
* **Storage Space:** Clear out Pokémon storage and your item bag.
* **Boosters:** Have Star Pieces and Lucky Eggs ready.
* **Mega Evolution:** Consider Mega Evolving a Grass-type Pokémon (e.g., Mega Venusaur) for bonus candy.
* **Route Planning:** Plan a route or spot with plenty of PokéStops and Gyms.
* **Friends:** Coordinate for trades and raid assistance.
