If you have any doubt that “Pokemon Go” is a cultural phenomenon, take a walk over to your local park, mall or museum and look for all the people staring at their phones, wandering in circles. If you want to make a new friend, walk up to any of them and say “Hey, did you hear about the Eevee hack?”

Users on Reddit recently uncovered the top-secret easter egg in the game, using an episode of the classic “Pokemon” cartoon series that is nearly 20 years old. Once you unlock it, the world’s most popular virtual reality game becomes even more fun to play.

If you’ve played the game, you’ve likely found that Eevee is in the same boat as Doduo, Rattata and Paras: Plentiful, easy to capture and not particularly strong enough to do anything with. So, Redditors went to work discussing how the cat-wolf-looking character was such a popular one in the “Pokemon” universe that perhaps there was more than meets the eye.

After recalling the 1998 episode “The Battling Eevee Brothers” (which focuses on an abandoned Eevee and  three brothers), fans theorized that if you changed the name of your captured Eevee to one of the brothers, it might take on the properties of the Pokemon they owned.

So, if you select your Eevee in the Pokedex and tap on its name, you can type in a new nickname. If you type in “Sparky,” it will evolve into a Jolteon. “Rainer” will result in a Vaporeon, while “Pyro” will get you a Flareon. With the character’s evolution now in your control, world domination — and the ability to gotta, gotta, gotta catch ’em all — is in the palm of your hands.
