To get Munna, you need Cut. Can't remember how you get Cut, but I think it's story-related so it's hard to miss. Once you beat the first Gym, you can get a Munna.Thanks for the fast respones. Is there an Isshu map with the names in 'normal' text on it? No japanese signs.
Edit: Where do I find Munna? Pokedex says to the east of the city with the first gym (I wanna know the name, that's why I need the map.) Do you only find it at night?
If you remember, taking the east route through a foresty area leads you to where the lady gives you a monkey, but it's a dead end. Looks to be in front of a factory, but there's a tree preventing you from entering.
Cut it, then upon trying to enter, storyline part happens. Then you keep walking and you'll see a Munna. Team Plasma stuff, you beat their butts and a Musharna appears and leads Munna out of danger. FOLLOW THEM and you'll find a patch of grass where you can find wild Munnas. I did catch mine at night but I doubt that it has to be night (alhough I wouldn't discount that possibility).
