That was...fast, jesus. [He's not really surprised by this answer, more surprised at himself for not realizing that would be the answer sooner. Because that's just what best friends do.]

But uh...there are a few different species out on the routes to the south and north. Ilex forest has some rarer Pokemon in it but that's like...a three or four day's walk away. Couple of hours if you can hitch another flying ride. And trust me, it takes a while to hunt down the rare stuff. Makes for a good camping trip though!
