Here's how to get around the holes in the Abandoned Ship:
1. Use Fly: You can't use Fly inside the ship itself, but you can use it to reach the top of the ship from the outside. This will let you bypass most of the holes.
2. Use Strength: Some of the holes are blocked by rocks. You'll need to use the Strength HM to move the rocks and get around the obstacles.
3. Use Flash: You can use the Flash HM to illuminate the area in the darker parts of the ship. This will help you see where the holes are and how to avoid them.
4. Use your Pokémon's abilities: Certain Pokémon have abilities that can help you navigate the holes. For example, a Pokémon with the "Float" ability can walk across water, which can be helpful in some areas of the ship.
5. Use the stairs: Some holes can be bypassed by taking the stairs. Look for nearby stairs that might lead around the holes.
Important Note: There are also some areas in the ship that have deep holes you can fall into. Be careful when navigating the ship, and don't go too close to the edge!
