[Help stuck on route 2 | Rejuvenation version 10]

Oh, I just figured that was her, since the appearance looks similar, and she's in the direction the thief went

Yes I did saw the walking tree, but it just ran away, wasn't that a pokemon?

Do I have to find it first?

[Help stuck on route 2 | Rejuvenation version 10]

Hi, I'm playing Rejuvenation Version 10, without having played any of the earlier versions before.

And all the walkthroughs or videos are about different versions and don't really fit.

 

On route 2 that girls stole my money, so I followed her and she wanted to fight me whe I caught her, but after I won, nothing happend.

And I can't enter the cave until I got my money back from her, it woudn't let me.

 

So I'm stuck. The thief only says: "Perhaps I'll actually just stay here."

 

I really hope some of you know why, or have an idea what I can do. Did I do something wrong or did I forget something??

Heeelp
