I want a Politoed with the his Dream World ability Drizzle. What area can I find him in?
"You can catch a Dream World Poliwag once you have 10,000 dream points if you go to Pleasant Forest. You then evolve that into Poliwhirl at level 25 and evolve it into Politoed by trading it with a king's rock. Since the Poliwag had its dream world ability (Swift Swim), the Politoed it evolves to also has its dream world ability of Drizzle." - Source
