Cottonee does not need to reach any particular level to evolve. You can use a Sun Stone on it and it will evolve into Whimsicott! Happy playing :)
Poliwhirl evolves into poliwrath when you use a Water Stone on it. It can also evolve into a politoed if you trade it while it's holding a King's Rock. Poliwhirle does not evolve by leveling up. If you give it a Water Stone it becomes a Poliwrath and if you trade it while holding a King's Rock it becomes a Politoad. Poliwhirl evolves into poliwrath when you use a Water Stone on it.
