How do you get fly in pokemon pearl?

You can't get Fly in Pokémon Pearl! This is because Fly is a move introduced in Pokémon Diamond and Pearl's sequels, Pokémon Platinum and Pokémon HeartGold and SoulSilver.

Here's why:

* No HM Fly: In Pokémon Pearl, you can only learn HMs like Cut, Strength, Rock Smash, and Surf. Fly isn't available.

* Limited Movement: This makes navigating the Pearl region a bit more time-consuming as you'll have to walk or use the bike to reach different areas.

If you want to use Fly in your Pokémon adventure, you'll need to play Pokémon Platinum, HeartGold, or SoulSilver.
