If you fancy some fresh air, I recommend the goblins slightly NW of treespeak. Respawns aren't too bad (and there is virtually no competition), and there's lemurs to kill time with in between pops if you want some filler foes. The game considers them around r43 if I remember right, but their terribly low hp, defense, weak tp moves, and evasion, would say otherwise. and they drop cookies

anyways, happy hunting~
