How To Catch A Goomy

First introduced in the sixth generation of main games, Goomy is a Dragon-type pokemon that resembles a small slug. While its evolutions, Sliggoo and Goodra, won't likely be found roaming Pokemon Go's overworld, Goomy has been an uncommon sighting since the Luminous Legends X event in 2021.

Because Goomy sightings are rather rare, you'll want to use a Pinap Berry for every catch you do, to maximize the amount of candies obtained per capture. Furthermore, a Silver Pinap Berry would be even better, as it would also help secure your chances of capturing the Goomy in the first place.

The main requirement you'll need to meet for the first evolutionary stage, is to gather an adequate number of Goomy candies. For starters, evolving Goomy into Sliggoo costs 25 candies, then another 100 to complete the evolution chain. You can get candy by:

  • Catching that particular species of pokemon. Remember that using Pinap Berries in the wild pokemon before throwing the pokeball will reward you more candies.
  • Walking with that pokemon as your buddy.
  • Feeding berries to that particular species of pokemon in a gym.
  • Transferring Goomy specimens will earn one candy for that species with each transfer.
  • Hatching Eggs will offer the most candy rewards if you happen to hatch the correct species.

Once you have enough candy, the next and final step involves weather manipulation.

Despite being a dragon species, this evolution chain has a unique preference for water and will only undergo its final evolutionary stage in the rainy weather. You could simply wait for a rainy day, but if you want a more efficiente method you can always use a Rainy Lure, which will also count for this step. The Rainy Lure can be obtained in the in-game Pokeshop for 200 pokecoins.

On top of helping evolve Sliggoo into Goodra, this type-specific Lure Module work the same way as standard Lure Modules, except it will only attract pokemon species of the Water, Electric, and Bug varieties.
