Pattern Bush

Found only in Pokémon FireRed and LeafGreen, Pattern Bush occupies a small offshore island north of Six Island, reached by a short Surf across the Water Path. Dense undergrowth blankets the area, making it an ideal habitat for the many Bug-type Pokémon living there. Curious bare patches of ground dot the terrain with no explained cause, though the Trainers battling among them have their own theories.
