Muchlax and Heracross
If you're like me and you REALLY want to know where heracross and munchlax are, this will tell you where to find them.
1.Get some sweet honey from the guy in Floroama Town's garden. I got about 10.
2.Slather honey on yellow trees throughout Sinnoh, BUT REMEMBER WHERE THEY ARE!!!!!
3.Come back in about 8-10 hours and if you're really lucky, you'll find one of them.
