Cartoon NetworkIf you've been playing "Pokémon GO," chances are you've wondered why Eevee seems to randomly evolve.
Unlike every other Pokémon in the game, Eevee can evolve into three different creatures: Jolteon, Flareon, and Vaporeon.

In the original game, Eevees were given special stones that made them evolve differently.
It turns out that there is a way to choose how your Eevee evolves in "Pokémon GO."

Redditor "smithnigel" figured the easter egg out by referencing the original Pokémon anime show.

"The Eevee Brothers from the original anime were named Rainer, Pyro, Sparky and they owned a Vaporeon, Flareon and Jolteon respectively. If you nickname your Eevee either Rainer, Pyro or Sparky, your Eevee will evolve into that desired Eeveelution!"
So change the name of your Eevee to one of the three Eevee Brothers, and it will evolve correspondingly.
Tech Insider
Many have already reported that the tip works, but some have said nicknaming an Eevee doesn't work the second time around.

So if you're trying to evolve multiple Eevees into Jolteons, for example, you may be out of luck.
