How do you get waterfall Pokemon white?

It's impossible to "get" a Waterfall Pokémon in Pokémon White, as the term "Waterfall Pokémon" isn't a recognized term within the Pokémon world.

Here's what might be confusing you:

* Water-type Pokémon: Pokémon White has many Water-type Pokémon you can catch! Some notable examples include:

* Oshawott (and its evolutions Dewott and Samurott): Your starter Pokémon.

* Tympole, Palpitoad, and Seismitoad: These are found in the water areas of the game.

* Simipour: A powerful Water-type found in the later stages of the game.

* The Move Waterfall: This is a powerful move that allows you to traverse waterfalls in the game, but it's not a Pokémon itself.

If you're looking for a specific Pokémon, tell me its name, and I can help you find it in Pokémon White!
