How do you get Pinsir in SoulSilver or HeartGold?

In Pokémon SoulSilver and HeartGold, Pinsir can be obtained by using the Headbutt move on certain trees in the Johto region. Headbutt is a move that allows you to shake trees to encounter Pokémon. Pinsir is a rare encounter, so you may need to try multiple trees before finding one. It is recommended to save your game before using Headbutt to increase your chances of encountering Pinsir.
