Question: what do you name eevee to evolve it?
Answer: You can choose which evolution form to evolve your Eevee into by naming it Sakura (Espeon), Tamao (Umbreon), Pyro (Flareon), Rainer (Vaporeon) or Sparky (Jolteon). This is an Easter egg reference to trainers and the Eevee Brothers from the original anime series.
