There is another way to get these original starter Pokemon, through Pokemon Go! However, discovering how to access the various Pokemon Let's Go hairstyles in the first place is quite a tricky thing. This one will show you the location of the game's singular Pokemon Daycare. This location is found in game in Kanto's Fuschia City - and you'll have to have reached Fuschia City naturally through the course of Pokemon Let's Go to access it.
How do I bring Pokemon that I've caught in my Pokemon GO account on my journey with me in Pokemon Lets go?
As part of this crossover, the Pokemon company, Game Freak and Niantic have released a brand new Pokemon into the game - Meltan!
Since Mythical Pokemon like Mew are tied to one per Pokemon Go account, you can not transfer Mew to Pokemon: Let's Go, Pikachu & Eevee!
When you transfer a Pokemon from Pokemon Go to Pokemon Let's Go you will be awarded a Mystery Box. At that point switch to your phone - and because the machines are synced up there'll be a clear icon of a Switch on the Pokemon menu screen. These packages are flying off hypothetical shelves at Amazon, and no surprise, considering that just the Switch and Pokemon game are selling for well over 350 at other retailers.
Remember, once Pokemon leave Pokemon Go they can not be retrieved back to that game. Hit that, then transfer Pokemon by pressing on them and confirming. Once they're in the game, they're in there for good. Select "Bring Pokemon", and then select a GO Park from the list.
Boot both Pokemon Go on your phone and Pokemon Let's Go on your Switch. But don't fret as there are plenty of customization options for your partner Pokemon Pikachu or Eevee.
