In Pokémon Let’s Go Pikachu and Let’s Go Eevee, Eevee has a unique gender difference; female Eevee can be distinguished by a noticeable love heart pattern on their tail. The Pokémon has unveiled a set of new videos that highlight Pokémon battles and wild Pokémon encounters. Players can become best friends with their Pikachu or Eevee and can pet, feed and even tickle them. Your partner Pokémon isn’t the only one that can travel along with you – you can have any Pokémon in the game as a traveling companion, too.
