Question: pokemon let's go pikachu how to get flute?
Answer: Thankfully, the Pokeflute is an item you get as a part of the story. Once you complete the Lavender Town Pokemon Tower quest (which involves you first clearing the Rocket Hideout in Celadon City and obtaining the Silph Scope to be able to unmask the ghosts in Pokemon Tower), Mr. Fuji will give you the Pokeflute.
