Poliwhirl evolves from Poliwag. It evolves from Poliwag at level 25, and can be evolved into either Poliwrath (by using a Water Stone) or to Politoed (by being traded by holding a King's Rock).
To get the Pokemon Poliwrath in Pokemon Diamond version you have to evolve a Polywhirl. To do this, you need to expose it to a water stone.
POLYWHIRL!
Polywhirl evolves using a waterstone and if you want a polytoad you will Need a kings rock and trade the polywhirl.
Poliwhirl evolves into Politoad when you trade it while it is holding a King's Rock.

Evee = Vaporeon Polywhirl = Poliwrath Sorry folks that's all i k n o w!
Yep.
Poliwhirl actually has a branched evolution, which means it can evolve to more than one pokemon. One way (Easiest and Classic) is to use a Water Stone so it will evolve into the Water/Fighting Pokemon Poliwrath. Or, you can give it a King's Rock and trade it to somebody so it will evolve into a Politoad ... and then trade it back of course :P.
Poliwhirl evolves 2 ways: Either use a water stone on it or trade it while it holds the item king's rock.
level up a poliwag
it can only evolve through stones. it may evolve into a Poliwrath with a water stone (get from Bill's father after showing him Staryu at Cerulean city), or a Politoad using King's rock (you get it from some guy at Mt. moon after you surf and find him)
polywhirl does not evolve by level to get a polywrath you have to use a water stone. If you want politoed, trade poliwhirl with somebody, and it will evolve into politoed.
