Pokémon Mystery Dungeon: Blue Rescue Team and Red Rescue Team/Friend Areas

Friend Areas are areas that can be reached by going left from your Team Base until you hit a pathway going left. When you reach that a list will appear with all of your recruited Pokémon listed. You can change the order they are listed in by hitting. Friend areas can be achieved three different ways. The first way, and the easiest way, is to buy them from Jigglypuff, located next to the bank in Pokémon Square. The second way to get Friend Areas is to rescue a Pokémon offering a Friend Area as an award. The third way is only available after you beat the game; some recruited Legendary Pokémon don't have buyable Friend Areas, so they will give you their Friend Area after you recruit them.
