The pokedex did indeed hold a plethora of information about the pokemon that lived surrounding the routes that he wanted to investigate. There was a fair amount to sort through, covering mountainous terrain to pokemon migration to favored breeding grounds. Figuring out from there what pokemon generally lived there was simple, if hard work involving a lot of listing. Some of the pokemon were rare to find near the paths, preferring living further in the wilds and only choosing to join humans that came out to seek them.

More zangoose came to see him while he studied, but still there was no sign of the one he wanted.
I am rolling for encounters with the zangoose that Lee's looking for, no luck so far on that.
