Wedgehurst

Walkthrough
Just north of Route 1 is Wedgehurst, a very small town that really has not much more than the Pokemon Lab and Train Station. Since you won't have access to riding the train at this point, there is nothing left to do but head to the lab so you can receive a Pokedex. Unfortunately, Professor Mongolia won't be there at the time of your arrival. Instead, Sonia, the granddaughter and Assistant of Professor Mongolia, will be the one to give your trainer a Pokedex. Once obtained, it will be time to head towards Route 2 near the northern part of the town.
