If you are trying to evolve Swirlix in Pokémon GO and the evolve option is still locked, there is a special requirement you may be missing. Unlike many Pokémon that evolve simply by collecting candy, Swirlix requires an additional buddy interaction before it can evolve.
Many trainers gather the required candy but are confused when the evolution button does not unlock.
This guide explains exactly how to evolve Swirlix Pokémon GO and how to complete the berry feeding requirement.
How to Evolve Swirlix Pokémon GO

To evolve Swirlix Pokémon GO you must complete two requirements before the evolution becomes available.
First, Swirlix must be set as your buddy Pokémon. While it is your buddy, you must feed it a certain number of berries. Once the requirement is complete and you have enough candy, the evolve option will unlock.
Follow these steps to evolve Swirlix:
Catch or obtain a Swirlix in Pokémon GO
Set Swirlix as your buddy Pokémon
Feed Swirlix 25 berries while it is your buddy
Collect 50 Swirlix Candy
Open the Swirlix page in your Pokémon storage
Press the evolve button once the requirement is completed
After completing these steps, Swirlix will evolve into Slurpuff.
It is important that Swirlix remains your buddy while feeding the berries so the progress counts toward the evolution requirement.
Why Swirlix Requires Feeding Berries to Evolve
The mechanic used to evolve Swirlix Pokémon GO reflects the Pokémon’s theme in the main Pokémon games. Swirlix is known as a cotton candy Pokémon that loves sweet foods, which makes berries a fitting requirement for its evolution.
In Pokémon GO, feeding berries represents Swirlix enjoying treats while building a bond with its trainer. After receiving enough berries, it becomes ready to evolve into Slurpuff.
Although the requirement is fairly simple, it often surprises players who expect Swirlix to evolve using candy alone.

How Much Candy Is Needed to Evolve Swirlix Pokémon GO
To evolve Swirlix Pokémon GO you will need 50 Swirlix Candy.
Swirlix Candy can be collected by catching Swirlix in the wild or during special events. Using Pinap Berries when catching Swirlix will double the candy reward and help you collect candy more quickly.
You can also transfer duplicate Swirlix to Professor Willow to gain additional candy.
Walking Swirlix as your buddy can also generate candy while you work toward feeding the required number of berries.
What Swirlix Evolves Into in Pokémon GO
When you evolve Swirlix Pokémon GO it evolves into Slurpuff.
Slurpuff is a Fairy type Pokémon known for its fluffy design and strong sense of smell. In Pokémon GO it can be used in certain PvP situations thanks to its Fairy typing and balanced stats.
Many players evolve Swirlix mainly to complete their Pokédex or to collect the full evolution line.
Because Swirlix does not always appear frequently in the wild, evolving one into Slurpuff can feel like a rewarding accomplishment.
Tips for Completing the Berry Requirement Faster
Feeding 25 berries to Swirlix is usually one of the easier evolution requirements in Pokémon GO.
Players can feed berries to their buddy Pokémon regularly while playing the game. Each berry fed will count toward the total required for the evolution.
If you have a large supply of berries from spinning PokéStops, you can complete the requirement fairly quickly. Simply continue feeding berries to Swirlix whenever the option becomes available.
Once the required number of berries has been fed and you have collected enough candy, the evolve button will unlock automatically.
Is Slurpuff Good in Pokémon GO
Slurpuff can be a useful Fairy type Pokémon in certain PvP leagues thanks to its typing and move options. While it is not considered one of the strongest Fairy type attackers in raid battles, it still has its place in some battle formats.
Many trainers evolve Swirlix primarily for collection purposes or to complete their Pokédex.
Its colourful design and unique evolution requirement make it a memorable Pokémon for many players.
Evolving Swirlix Pokémon GO
Understanding how to evolve Swirlix Pokémon GO becomes simple once you know about the berry feeding requirement. Instead of evolving with candy alone, Swirlix must be set as your buddy and fed 25 berries before the evolution becomes available. After completing this requirement and collecting 50 Swirlix Candy, the evolve option will unlock and Swirlix will evolve into Slurpuff.
Although the requirement may initially surprise some players, it adds a fun interaction with the buddy system in Pokémon GO. By feeding berries regularly while Swirlix is your buddy, you can quickly evolve Swirlix Pokémon GO and add Slurpuff to your collection.
