Eevee is another Iconic Pokemon that you can catch in Pokemon Sun and Moon. You will have to progress a bit into the game before you can find one. Check out this guide to find out Where To Catch Eevee In Pokemon Sun And Moon!
Where To Find Eevee In Pokemon Sun And MoonYou cannot catch Eevee until you hit the second Island. Early on your mission will be to go to a Pokemon Ranch. On the way to the Pokemon Ranch you can find Eevee spawns right before the Town near the Ranch. It is kind of rare but I had a couple spawn on me during my play time. You can also find them on the other side of the map, on Route 5 coming down from the Ranch. Eevee will often call for extra help so be prepared for that. You can still evolve Eevee into multiple different forms, more then I even remember. I caught mine at night, but I don’t think that matters for Eevee.
When I start finding Stones that Eevee can use, I will add those to the guide to help people find them as well.
Water Stone – Found this pretty quickly after getting Eevee. It is on Akala Island, Route 8 near the Forest Trial. Before entering the forest there is some water to the left. Enter the water and the stone is under the water near the guys training Karate.
Fire Stone -This one is also on Akala Island, after the grass Trial. You can find it in Diglett’s cave next to the stair case leading up. Use the rock smash ability to get back there for the item.
Stone Store – This is a Stone Store on Akala Island as well. You can find it in Koni Koni city as you start to finish the island, it is the place with the Fossil inside as well.
Moss Stone – You can find this in the Jungle where you take the trial. Thanks to Jay Carr for the info in the comments.
