Perhaps you're thinking of something else? Could you be more specific about what you mean by "turn back cave" and what part of the map you're talking about? For example, are you:
* Trying to find a specific item or Pokémon in a cave? If so, I can help you find the location.
* Confused about the layout of a cave? I can guide you through it.
* Looking for a specific event that might happen in a cave? I can tell you what triggers it.
Please provide more details so I can assist you better!
