Do the unkowns come out on there own in weepth chamber Pokemon LeafGreen?

You're likely referring to the "Unknown" Pokémon, which are found in the Whirl Islands of Pokemon LeafGreen. They are not found in the Weepth Chamber.

Here's how you encounter Unknown Pokémon:

* Whirl Islands: You'll encounter these Pokémon in the Whirl Islands, which are located to the east of Cinnabar Island.

* Specific Locations: Each Unknown Pokémon appears in a specific location within the Whirl Islands, and you need to find them by exploring.

* Rare Encounters: They are relatively rare, and you might need to search for a while to find them all.

Tips for Finding Unknown Pokémon:

* Use Repels: Repels will prevent weaker Pokémon from appearing, making it easier to find Unknown.

* Explore Thoroughly: Carefully explore every corner of the Whirl Islands, as they can be easily missed.

* Search for Hidden Grooves: Some Unknown are found in hidden grooves within the island, so pay attention to the terrain.
