However, you can use Wingull's Fly HM to travel between different locations on the map. Here's how it works:
1. Learn Fly: You'll need to teach Wingull the Fly HM. You can obtain it from the Pokémon Fan Club in Slateport City.
2. Use Fly: Once Wingull knows Fly, you can use it in the field by pressing the Select button and selecting "Fly".
3. Choose a Destination: You can then choose a location you've already visited from a list.
4. Take to the Skies: Your Wingull will fly to the chosen location, saving you time and effort.
Important Note: While Wingull can use Fly, it doesn't mean you can control it in flight. You can only select from pre-determined locations you've already visited.
