I'm trying to find trapinch and shinx in white forest, but I can only find elekid and wurmple? I have white version, and I double checked to make sure they were in the white forest, but can't find them???
You need to expand your residence. Right now, you only have Silvia and Robbie. Use Entralink with a Pokémon Black player to expand your population. Shinx requires Doug, and Trapinch needs Eliza.
