You have to manually catch it, it cant evolve in the game its a starter in, it doesent have a 3 stage line and its not fire gras

Eevee's technically a starter. People also theorize that Clefairy is as well.

It IS your first pokemon but it is so different from other starters. And I’m just shocked by the fact that people think clefairy is a starter

There was a pokemon manga once where Red's first pokemon was a clefairy.

I mean in the games

Lol
