Grookey Community Day 2026 Guide: Shiny, Evolution & How to Get

Part 1. Is Grookey Shiny in Pokémon Go? How to Get It?

Yes! shiny Grookey in Pokémon Go is available for the first time during this Community Day event. Trainers will have a good chance (1 in 20) to catch it in the wild and add to their collection.

Where Can I Find Shiny Grookey in Pokémon Go?

Finding a shiny Grookey involves participating in various event activities that offer a boosted 1 in 20 encounter rate. From wild exploration to specialized research, multiple methods exist to secure this rare Pokémon.

Wild Spawns

During the event hours, Grookey in Pokémon Go will spawn everywhere more often. That means shiny Grookey can appear naturally on the map while you’re exploring.

Community Day Special Research

For US$1.99, you can buy a Grookey Community Day Special Research ticket. Completing these tasks will reward you with guaranteed Grookey encounters, including 3 with special backgrounds.

Field Research Task

There will also be Community Day-themed Field Research tasks. These will involve catching Grookey and give rewards like Stardust, Great/Ultra Balls, and bonus Grookey encounters.

Snapshot Surprises (Photobombs)

During event hours, taking snapshots of your Pokémon often triggers a "photobomb" by Grookey. After the surprise encounter, Grookey will appear in the wild on the map. These encounters have the same elevated Shiny rate as wild spawns.

Defeating Thwackey will cause Grookey to spawn around that Gym for 30 minutes. These spawns still have the high Community Day Shiny odds, giving you a second chance to find a Shiny!

Lure Modules & Incense

While these are common items, they are crucial during Community Day because they typically last for 3 hours instead of 30 minutes. Using them ensures a constant stream of Grookey encounters, significantly increasing the mathematical probability of finding a Shiny.

Part 2. What Does Grookey Evolve into? Full Evolution Line & 100% IV.

Now that you know how to catch Grookey in Pokémon Go, it’s time to look at what this chimp Pokémon evolves into.

In short, the Grookey evolution line starts with the playful Grass-type Grookey and ends with the mighty Gigantamax Rillaboom in Pokémon Go.

How to Evolve Grookey in Pokémon Go?

To evolve Grookey, you first need to accumulate enough Grookey Candy in Pokémon Go. Then:

• Evolve Grookey into Thwackey by spending 25 Candy.
• Evolve Thwackey into Rillaboom by spending 100 Candy.

Note that if you’re after Gigantamax Rillaboom in Pokémon Go, you’ll need to encounter it in dedicated Max Raid Battles.

During the Grookey Community Day event, evolving a regular Grookey into Rillaboom won’t make it a Gigantamax Rillaboom.

How to Identify a 100% IV Grookey?

A Grookey in Pokémon Go with 100% IV means its Attack, Defense, and Stamina values are all perfect. You can check a 100% IV Grookey by following three ways:

• In-Game Appraisal : Check the "Appraise" feature; a 100% IV Grookey will show a Red Badge with the Attack, Defense, and HP bars all maxed out at 15/15/15.
• Search String Shortcut : Enter “four star” into the search bar to filter for perfect IVs, or use four star & Grookey to find them specifically.
• CP (Combat Power) Benchmarks : Identify potential hundos by their CP values at specific levels, such as 465 CP for Level 15 or 620 CP for Level 20.

A 100% IV Grookey will have the maximum stars and best stat numbers, making it ideal to evolve into a strong Rillaboom.

Part 3. Is Grookey Worth Evolving into Rillaboom in Pokémon Go?

To see if Rillaboom is right for your playstyle, you need to check its stats. Here is a breakdown of its power and attributes.

1Rillaboom's Stats & Max CP

Rillaboom’s max CP is at 3758 at Level 50 with the following base stats:

• Attack: 239
• Defense: 168
• Stamina: 225

The above stats make Rillaboom in Pokémon Go strong for raids and trainer battles. Its balanced stats give it decent endurance and punch as a Grass attacker.

2Rillaboom's Best Moveset in PvP & PvE

In PvP

• Rillaboom’s Best Moveset: Razor Leaf (Fast) + Grass Knot (Charged)
• This combination gets good damage output and helps in many battle situations.

In PvE

• Rillaboom’s Best Moveset: Razor Leaf (Fast) + Grass Knot (Charged)
• This combo also works well against Gym defenders and Raid bosses that are weak to Grass attacks, like Water and Ground.

3Is Rillaboom Good in Pokémon GO? PvP & PvE Performance Guide

Rillaboom is a top-tier Grass-type meta pick in Pokémon GO. Following the January 2026 Community Day, its exclusive move Frenzy Plant makes it a powerhouse for Ultra League PvP and high-DPS Water-type Raids. This guide breaks down Rillaboom’s best moveset and competitive rankings.

Rillaboom PvP Performance: Great, Ultra, and Master League

In Pokémon GO PvP, Rillaboom’s viability depends heavily on its exclusive move, Frenzy Plant. Without this move, it is largely outclassed by other Grass-type starters like Venusaur or Meowscarada.

Pro PvP Tip: Evolution timing is key. To unlock Rillaboom's full potential, you must evolve Grookey during the January 18, 2026, Community Day window to obtain the legacy move Frenzy Plant.

PvE Analysis: Best Grass-Type Raid Attacker

Rillaboom is a top-tier Grass-type attacker in Pokémon GO PvE, excelling in Raids and Gym battles against Water, Rock, and Ground-type bosses. With its signature move Frenzy Plant, Rillaboom’s DPS rivals elite counters like Mega Venusaur and Kartana, making it the ultimate "budget" powerhouse for F2P players.

This performance peaks during Sunny or Clear weather, where the tactical weather boost allows Rillaboom to successfully solo or duo specific Tier 3 and Tier 5 raids.

Part 4. Grookey Vs Scorbunny Vs Sobble, Which Is Better?

Choosing between Grookey, Scorbunny, and Sobble can be tricky for Pokémon GO players, especially since each starter offers different strengths in stats, typing, and future evolution potential. Below is a detailed comparison to help you decide which one fits your playstyle best.

Scorbunny evolves into Cinderace, a Fire-type Pokémon focused on speed and offensive. Its 3412 max CP is slightly lower than Rillaboom’s, but it feels quicker in battles.

Fire types shine against Grass, Bug, Ice, and Steel Pokémon. This makes Scorbunny a strong offensive pick for fast fights.

Sobble

Sobble becomes Inteleon, a Water-type Pokémon with good versatility and solid performance. It has a max CP of 3351, which is very similar to Cinderace’s and is excellent against Fire, Rock, and Ground Pokémon.

FAQs about Grookey in Pokémon Go.

Is Rillaboom rare in Pokémon GO?

In Pokémon Go, Rillaboom isn't inherently super rare, especially since its base form (Grookey) and evolutions appear during events like GO Fest and Community Days, but obtaining its powerful Gigantamax form often requires timed events, special raids, or trading, making that specific version less common and desirable for dedicated players.

What Is Grookey Weak Against?

Grookey is a pure Grass-type Pokémon, making it vulnerable to Fire, Flying, Bug, Ice, and Poison-type attacks. Trainers should avoid using Grookey against these types, as it will take increased damage in battles and raids.

What Attacks Does Grookey Have?

In Pokémon GO, Grookey mainly uses Grass-type fast and charged moves that focus on consistent damage output. It can also learn the Normal-type move Scratch, which provides basic coverage but is generally less effective in competitive battles.

Is Rillaboom a good dynamax in Pokémon Go?

Rillaboom possesses the highest overall stats amongst all starter Pokemon. It has ~20% more Attack than Venusaur and roughly equal bulk. It is currently slightly outclassed by Gigantamax Venusaur due to the sheer power of G-Max moves, and even more out-classed by its own Gigantamax forme.

How Strong Is Grookey?

Grookey itself has average stats and limited battle performance in Pokémon GO. Its real value lies in evolving into Rillaboom, which offers much stronger attack power, better move options, and greater usefulness in raids and PvP battles.

Final Thoughts

To wrap it all up, Grookey in Pokémon Go offers great value for both new and experienced trainers. With the Community Day upcoming, Grookey shiny chances are well over boosted and also features a strong final evolution: Rillaboom, which knows the charged attack, Frenzy Plant.
