When players transfer a Pokémon from their game into their Pokéwalker, they can select which route they would like to take their Pokémon along. Depending on which route the player takes (such as in a grassland or by the sea), they will encounter different wild Pokémon and items. When players first begin their journeys with the Pokéwalker, the list of routes they can select from is short. But, the more players take a stroll with their Pokémon, the more routes will appear and the more Pokémon and items they will be able to get.
