If you are trying to evolve Sliggoo in Pokémon GO and the evolve button does not appear, there is a special requirement you may be missing. Unlike many Pokémon that evolve simply by collecting enough candy, Sliggoo requires a specific weather condition or lure module before it can evolve.
Many trainers gather the required candy but are confused when the evolution option remains locked. This guide explains exactly how to evolve Sliggoo Pokémon GO and the easiest ways to meet the rain requirement.
How to Evolve Sliggoo Pokémon GO
To evolve Sliggoo Pokémon GO you must meet two conditions before the evolution becomes available.
First, you must collect enough candy for the evolution. Second, you must either be experiencing rainy weather in the game or be standing near a Rainy Lure Module.
Follow these steps to evolve Sliggoo:
Catch or obtain a Goomy in Pokémon GO
Evolve Goomy into Sliggoo using 25 Goomy Candy
Collect 100 Goomy Candy
Wait for rainy weather in the game or find a Rainy Lure Module
Open the Sliggoo page in your Pokémon storage
Press evolve once the Goodra silhouette appears
After completing these steps, Sliggoo will evolve into Goodra.
If it is not raining in game and you are not near a Rainy Lure Module, the evolution option will remain unavailable.
Why Sliggoo Requires Rain to Evolve
The evolution mechanic used to evolve Sliggoo Pokémon GO reflects how the Pokémon behaves in the main Pokémon games. Sliggoo is known for its slimy, moisture loving body and evolves under rainy conditions.
Pokémon GO recreates this mechanic by requiring rainy weather in the game before the evolution can happen. If the weather system shows rain on the map, the evolution button will activate automatically.
This small detail often causes confusion for players who do not realise the weather requirement exists.
How Much Candy Is Needed to Evolve Sliggoo Pokémon GO
To evolve Sliggoo Pokémon GO you will need a total of 100 Goomy Candy.
Goomy Candy can be collected by catching Goomy in the wild, participating in events where Goomy appears more frequently, or by walking Goomy or Sliggoo as your buddy Pokémon.
Using Pinap Berries when catching Goomy will double the candy reward and make it much easier to reach the evolution requirement.
You can also transfer duplicate Goomy or Sliggoo to Professor Willow to gain additional candy.
What Sliggoo Evolves Into in Pokémon GO
When you evolve Sliggoo Pokémon GO it evolves into Goodra.
Goodra is a Dragon type Pokémon known for its bulky stats and impressive design. It is one of the final evolutions from the Kalos region and is popular among players because of its rarity and powerful appearance.
While Goodra is not the absolute strongest Dragon type attacker in Pokémon GO, it still has respectable stats and is a valuable addition for players building a Dragon type team.
Many trainers evolve Sliggoo primarily to complete their Pokédex or to add a powerful Dragon type Pokémon to their collection.
How to Use a Rainy Lure Module Instead of Waiting for Rain
If you do not want to wait for rainy weather in Pokémon GO, there is another option available.
Rainy Lure Modules can be placed on PokéStops and simulate the rainy conditions needed for certain Pokémon evolutions. When a Rainy Lure is active, it allows Sliggoo to evolve even if the in game weather is not showing rain.
Players can purchase Rainy Lure Modules from the in game shop or occasionally receive them from events or special research rewards.
Standing within range of a PokéStop with an active Rainy Lure will allow you to evolve Sliggoo immediately if you have enough candy.

Is Goodra Good in Pokémon GO
Goodra is a strong Dragon type Pokémon with good defensive stats. While it may not always outperform top tier Dragon attackers in raids, it is still a solid Pokémon with respectable durability.
Many players evolve Sliggoo mainly because Goodra is a fan favourite Pokémon with a unique design. Its rarity and connection to the Kalos region also make it an appealing addition to a Pokémon collection.
Because Goomy is not always a common spawn, evolving Sliggoo into Goodra can feel like a rewarding achievement.
Evolving Sliggoo Pokémon GO
Understanding how to evolve Sliggoo Pokémon GO becomes simple once you know about the rain requirement. Instead of evolving anywhere with candy alone, Sliggoo must be evolved during rainy weather or while standing near a Rainy Lure Module. Once this condition is met and you have collected 100 Goomy Candy, the evolve option will unlock and Sliggoo will evolve into Goodra.
Although the weather requirement can sometimes slow the process, it adds an interesting twist to the evolution system in Pokémon GO. By watching for rainy weather or using a Rainy Lure Module, you can easily evolve Sliggoo Pokémon GO and add Goodra to your Pokémon collection.
