From Bulbapedia, the community-driven Pokémon encyclopedia.
Teakwood Forest (Japanese: チークのもり Teak Forest) is a location in Pokémon Ranger: Guardian Signs.
It is located west of Cocona Village and south east of Rasp Cavern on Renbow Island. The first Pokémon Pinchers are battled here, where they attack with a Croagunk and a Buizel.
It is also home to the Quest "Fly, Starly!", as the player has to chase a Starly there.
