First off, learn to spell Waterfall and Platinum. Also, not only is your spelling less than desirable, but the grammar needs some work.
"How do you get the HM Waterfall in Pokemon Platinum?" is probably what you were going for.
Regardless, after you beat Volkner in the Sunnyshore City Gym, go North on the ground level of the town, where Jasmine (circa Pokemon Silver/Gold/Crystal) will give you Waterfall.
Good luck, fellow Trainer. I recommend Pokemon in the mid-to high-50s for the Pokemon League. 60s would be good to play it safe in case of type disadvantages.
it's in the ice path
yes you have to put game in your system that you have go to migrate.
Go to Route 1 and surf over to Route 18.
you have t find the hm then you teach it to a Pokemon. then if it is fly of defog you just go to the Pokemon screen and select the Pokemon and it will use it if it is strength rocksmash or watterfall and rock climb then you go up to the thing you want to go through and press a and it will use it. come to my message board if you have anyother question.
You sell them in sinnoh parks at oldale city.
get it from the lady outside of your 8th cym badge
You need the HM watterfall to gain access to higher levels of Meteor falls. Then follow the path around until you get to a narrow area full of water, use surf to cross. There is a small patch of ground. This is the only place you can find one. Everyone says its rare but I got it first try.
go to north sea in sunnyshore and your riaval will battle you and if you beat him a girl called jasmin gives you HM watterfall then surf north andand then yuol come across a waterfall and go up it then do a hard maze then its the elite four
Your Pokemon cannot level up on Pokemon battle revolution
just battle against other Pokemon to level up
By training your Pokemon.
Pokemon level up when they receive experience from battles. When your Pokemon defeats another Pokemon in battle, it receives EXP.
