Question: how do you get the shiny charm in pokemon let's go?
Answer: After capturing all 151, head to Celadon City and visit the Game Freak offices. (This cute Easter egg is found in the back of a building demarcated by a solitary Poliwhirl.) The game director inside will hand over a Shiny Charm item, which brings the number down from one in 4,096 to one in 1,365.
