you can either get lucky by putting honey on a tree, otherwise make sure you have battled
every trainer to get burmy recorded on your poke'dex

Well really, it is just that u need to buy honey off a man in the forest in the north-west
corner of Floaroma Town then slather it on golden trees found in random, but the same
spots, around the Sinnoh region and if u start to see one of the golden trees with honey
slathered all over it's bark, SAVE YOUR GAME! Then hit the A button. If u did not find a
burmy, turn it off and back on or reset by pressing L,R,Select and Start simultaneously.
Then just go into your game and examine the tree once again, repeat until u find a burmy,
if u wish to see/obtain burmy's evolutions, you need to get burmy to lvl 20 and for
mothim, it must be a male and for murmadam, female. If u got the wrong type, u mut repeat
process, but if u haven't saved it from when u saved at honey tree, reset/ turn off and
back on.

burmys r in the great marsh..idk how 2 see evolve form tho....and what do u do after u
beat crasher wake...like what city do u go 2?
