I Love Munchlax alot so I really want one but I cant seem to find it any where?
You have to put honey on a tree, then wait for 12 hours for a Pokemon to appear on the tree. It will not always be Munchlax however. The trees you can put honey on are Gold/Yellow in color. You can also breed a Snorlax holding the Full Incense.
You can also get a munchlax by an egg.
