The normal type Pokémon Eevee is rarely encountered in the wild of Pokémon GO, but as Pokémon GO players have gone further into Professor Willow’s second set of research tasks for Celebi, it’s come to light that you need to evolve some Eevees into specific forms, Espeon and Umbreon.

If you decide to use up 25 of your Eevee candies and hit Evolve on any of your Eevees, the game randomises which Eeveelutions you end up with. So if you’re looking for a specific type, that’s not going to work. Luckily, there are two ways of picking a specific Eeveelution.

The Naming Trick

You can target your Eeveelution by renaming the Eevee you want to evolve to the name of one of The Eevee Brothers from the original anime.

Rainer evolves into water-type Vaporeon
Sparky evolves into lightning-type Jolteon
Pyro evolves into fire-type Flareon
Sakura evolves into psychic-type Espeon
Tamao evolves into dark-type Umbreon

It’s important to note that the Naming Trick only works once per name, so choose your Eevee wisely! Also, choosing this method to get an Espeon or Umbreon won’t work for the Celebi quest.

The Walking Trick

Gen 2’s Umbreon and Espeon also have a second evolution method, which is the method that Professor Willow asks you to use for your Celebi quest. With your chosen Eevee as your buddy, you need to walk with them for 10km (two candies) and then either evolve it during the day to get Espeon, or at night to get Umbreon.

It’s also important to note that you need to have that Eevee as your buddy when you do the evolution, if you swop them out first you’ll get a randomised evolution instead, so don’t waste your walking time! Make sure the game is reflecting as night or day as well, and that you have tracked 10km and earned two candies to get your desired Eeveelution.

Gen 4’s Eeveelutions

There’s still no official word on when we’ll start seeing Gen 4 Pokémon in the wild, though it should be coming up soon. With Gen 4, Eevee should also get two new evolutions, the grass-type Leafeon and ice-type Glaceon. It’s safe to say that the naming trick will work for them as well, but we’ll need to wait to see what those specific names are going to be.
