No Pokémon game is really complete without Eevee, and to no one's surprise, the bushy-tailed fan favorite is also in Pokémon Sun and Moon.
Eevee is arguably one of the most popular Pokémon in the entire series, and aside from its unassuming appearance, it's probably because it has many evolutions with various elements, including the lightning type Jolteon, water type Vaporeon, fire type Flareon, psychic type Espeon, dark type Umbreon, fairy type Sylveon, grass type Leafeon and ice type Glaceon.
Take note there are no new evolutions for Eevee in Pokémon Sun and Moon, but the required materials and conditions to evolve it have been changed a bit.
How To Evolve Eevee Into Jolteon
Eevee turns into Jolteon when you give it a special stone called Thunder Stone.
To get one, head to the back of the caravan found at the Fossil Restoration Center in Route 8. Alternatively, you can get one by playing minigames at Poké Pelago or buy one in Konikoni City for 3,000 credits.
How To Evolve Eevee Into Vaporeon
Put simply, you're going to need to expose Eevee to a Water Stone to get a Vaporeon.
As for where you can nab the special stone, you can find it in Route 8 in the water south of the small island, or you can just buy one in Konikoni City for 3,000 credits or win some via Poké Pelago.
How To Evolve Eevee Into Flareon
Just like the others, Eevee needs a special stone to evolve into Flareon, and this time around, it's a Fire Stone.
You can get one in Konikoni City for 3,000 credits or through Poké Pelago. However, you can grab a freebie at Diglett's Tunnel in the northwest corner, but you're going to need Tauros for this one.
How To Evolve Eevee Into Espeon
Unlike the first-generation evolutions of Eevee — Jolteon, Vaporeon and Flareon — Espeon is a bit trickier to get.
First off, you're going to have to raise Eevee's friendship level to at least 220 by having it hold a Soothe Bell, giving it various Berries and vitamins and winning a lot of battles without it fainting.
However, there's a trick to increase your Pokémon's happiness quickly. The gist of it is that you need to get two TM items that Eevee can learn and repeatedly teach it the same moves over and over again, as it becomes happier each time it learns one.
After that, make it gain a level during daytime, and it should evolve into Espeon.
How To Evolve Eevee Into Umbreon
You just have to follow the same steps on how to get Espeon to make Eevee evolve into Umbreon, but this time, you have to raise its level at night.
How To Evolve Eevee Into Sylveon
To start things off, get Eevee to learn a Fairy type move. Next, head to Pokémon Refresh via the menu and earn two hearts by feeding it Poké Beans and petting it.
When everything's all set up, it'll evolve into Sylveon when it levels up.
How To Evolve Eevee Into Leafeon
To point out the obvious, have Eevee in your party and go to Lush Jungle near Route 8.
There, look for the big rock that will prompt this message when you interact with it: "The surface is covered with moss. It feels soft to the touch."
All that's left to do now is to keep on battling the Pokémon in the area until Eevee evolves into Leafeon.
How To Evolve Eevee Into Glaceon
To get Glaceon, you're going to follow basically the same instructions with Leafeon's evolution, but instead of a large mossy rock, you're going to need an icy one.
That said, just head on over to the Pokémon League and go inside the mountain to find it. To make sure you got the right one, it should say this when you interact with it: "It's a rock that is covered in ice. Touching it seems likely to freeze you solid!"
As everyone may have figured out by now, just battle with the Pokémon there until Eevee evolves.
Where To Find Eevee
If you're reading this short guide, then you probably already have an Eevee, but for those who don't have one yet, you can catch it on Akala Island, the second island you'll arrive at in your adventure.
As to where Eevee exactly is, you can encounter one in Route 4, near Heahea City.
Long story short, Eevee is essentially a must-have since the beginning of the Pokémon franchise, so much so that a ton of Pokémon GO players are in pursuit of a Jolteon, Vaporeon and Flareon.
