I tried doing some research while also keeping myself fairly unspoiler (I'm currently at Serra's gym) and I found out that currently Munchlax is currently obtainable only via trade later in the game, If someone has any excess Munchlax I would love to have one. I used to use one in competetive Pokemon in x/y sun/moon era and I loved the Thick Fat snorlax. I'm sure we could work some trade out though I don't have that much... yet.
