Use Honey on a golden tree. The chance is VERY low... like 1% and I'm not exaggerating. What most people don't know is that if you don't get a Munchlax in a tree and you try again, the probability will go lower. Do it on AS MUCH trees as you have Honey. Go back to each tree exactly six hours after you slather honey on it.
In Platinum, you can get Munchlax, Cherubi, Combee, Burmy, Wurmple, Heracross, and Aipom. Munchlax is THE hardest to get.
Munchlax > lvl up with max happiness > Snorlax
a honey tree
To find munchlax put honey on a tree and wait until a munchlax appears or breed snorlax.
You get a Munchlax by spreading honey on a honey tree. But they hardly even show up so tjats a pain
There are sweet smelling honey trees in the sinnoh region. It's only natural that munchlax is constantly searching for food, so it's obvious that they will go for the honey that you slather on trees. They are much more common in this game than they were in diamond and pearl.
Munchlax > lvl up with max happiness > Snorlax
You get it from honey trees
level it up
munchlax does not evolve at a sirten lvl it evolves when its friendship is fully maxed out
Your rival in diamond/pearl/platinum
a honey tree
in honey trees

There is no trainer in platinum that is willing to trade a munchlax.
It evolves via happiness
You can slather some honey on a tree and it might come. (Munchlax is very rare though)
munchlax is a pretty hungry Pokemon so i guess a lot of honey
