How to get Grookey and evolutions Thwackey and Rillaboom in Pokémon Go

As part of the Max Out Season in Pokémon Go, players are now able to encounter the beloved Pokémon Grookey, along with its evolutions Thwackey and Rillaboom. This charming little monkey, celebrated as the Grass-type starter from Generation 8, offers a delightful addition to any trainer’s roster, especially since its much-anticipated release in 2020. If you’re a seasoned Pokémon Go enthusiast eager to enhance your collection, you’ll definitely want to add Grookey to your lineup.

How to Catch Grookey in Pokémon Go

Grookey made its official appearance during the GO All Out event held in September 2024. Here are the ways you can catch Grookey during this event:

  • Found in the wild
  • Hatching from 5km eggs
  • Completing event-exclusive field research tasks (e.g., catch 8 Pokémon)
  • Opting for ‘Adventure With Grookey’ during the Galar Calling quest

When engaging with the Galar Calling special research quest, keep in mind that choosing this route will exclusively focus on Grookey. This means while you can enrich your Pokédex with Grookey’s evolution line, you won’t be able to access the other paths once a choice is made. So, if you have yet to begin the Galar Calling quest and are a fan of Grookey, this is certainly the way to go.

Beyond the guaranteed Grookey obtained through this quest, encountering one in the wild remains the simplest method. Remember, as a starter Pokémon, Grookey tends to be more elusive than other wild Pokémon. Be prepared to use a variety of Poké Balls and berries to help secure the catch. Fortunately, during the GO All Out event, Grookey’s spawn rate is reportedly increased, providing a greater chance of encountering it.

If your strategy involves completing field research tasks, note that these tasks can also yield encounters with Scorbunny and Sobble, which may necessitate multiple completions to successfully catch Grookey. Additionally, PokéStop tasks change daily and can vary, adding an extra layer of challenge. Joining a local Pokémon Go community can help you track down the tasks you seek.

If you’re considering hatching Grookey from a 5km egg, this method requires some patience as you must walk a certain distance, and there are other Pokémon in the egg pool. Keep in mind that Grookey will only hatch from 5km eggs collected during the GO All Out event—not those obtained prior. While it’s worthwhile to hatch new eggs, we recommend focusing your efforts elsewhere for the fastest way to find Grookey.

Ultimately, securing at least one Grookey during the GO All Out event is essential for your Pokédex and a first step towards evolving this delightful Pokémon. While it’s likely that Grookey will remain in the 5km egg pool later on, its future spawn rates are unpredictable, meaning now is the best time to catch it.

Evolving Grookey: From Thwackey to Rillaboom

To evolve Grookey into Thwackey, you will need 25 Grookey Candy, followed by 100 Grookey Candy to achieve Rillaboom. In total, this means you’ll require 125 Grookey Candy to complete its evolutionary line.

To maximize your Candy collection when catching Grookey, utilize a Pinap Berry or its silver variant before throwing a Poké Ball, as this will double the Candy you receive upon capture. Keep track of the Grookey you’ve caught and consider transferring those with unsatisfactory IV stats to increase your transfer candy. Additionally, having Grookey as your buddy Pokémon will gradually earn you Candy as you explore.

If you’ve chosen the Grookey route in the Galar Calling quest, you will also earn sufficient candy to fully evolve one Grookey into Rillaboom. Should you prefer the IV stats of the Grookey obtained from this quest, additional Candy can enhance its CP level.
