Pokewalker (blue lake) or at the safari zone on water or good rod.
surf on water or get a fishing rod
Poliwag can be caught by using any kind of rod in Route 43 (Pokémon Heart Gold / Soul Silver)
32
use the water stone
You can find Poliwag by surfing on routes 227 and 228.
Poliwag evolves into Poliwhirl at level 20. if you want a Poliwrath use a water stone on your Poliwhirl but if you want a Politoed give your Poliwhirl a King's Rock and trade it.
Poliwrath cannot be found in the wild. It can only be obtained via a water stone. You must use the water stone on a poliwhirl. To get a poliwhirl, you must evolve a poliwag.
first you gotta either get a poliwag and evolve it or just catch the second form then you gotta give it the kings rock and trade it. I know someone who can make shiny politoads but he is not doing it right now
I'm sorry, but you will have to trade from Pokemon LeafGreen or FireRed. There is no way to find a Poliwag in the wild in Emerald.
You can't catch a poliwag in Pokemon Sapphire. You have to trade from Pokemon Fire Red or Pokemon Leaf Green.
to get a poliwag, you must obtain a good rod or a super rod. next, fish in cerulean city or the lake near vermilion. they are the most common places to find poliwag. hope this helps!
You'll need to trade for it.
