Route 101 is a Hoenn route located between Littleroot Town and Oldale Town. As the first route of the region, it is also the route with the lowest leveled Pokémons. With no particular points of interest, it is recommended to quickly move on to the next locations after having captured all desired pokemons.
Rachel's friends Quest (Rachel)
Right next to the south end of the route is located Rachel, an NPC that begins a unique quest. She explains the goal of the quest; inspired by the Paperclip trade, she will give a Pokéball, and she asks the player to find a total of 9 of her friends who will exchange the Pokéball for something a little better each time. While the Pokéball can be used, it will be necessary to purchase a new one in order to continue the quest.
The first friend to find will be Taylor, who can be found in either Oldale Town, Rustboro City's Devon Corp 3F, or Rustboro City's gym.
