Question: pokemon let's go pikachu how to get aerodactyl?
Answer: The first step to acquiring an Aerodactyl in Pokemon: Let's Go Pikachu and Eevee is to complete the Old Amber quest. Once one of your Pokemon learns the Chop Down Secret Technique, head back to Pewter City. Once there, go behind the Museum of Silence building and use the Chop Down skill near the tree.
