Am I stuck in this battle forever? I cannot do any damage to this thing. I am new and I don't understand that whole battling concept...

Go here to forfeit the battle.

There's a basic battling guide to new battlers here but I'm happy to help you with any questions you have.

Thank you so much I didn't see it in the guide - I must not have looked hard enough! haha

Don't worry about it, it's easy to overlook =) if you have any questions, send me a comment, I'm happy to help
