The Wonderland Board

Hello everyone...
I would like to ask you something special...
One friend in my channel in youtube asked me what it needs to catch this purple star in Star Town...
The blue star says that only the most experienced adventurers can catch it...
Really...you need to wait until you will get enough experience for catching it or it needs something else?
Maybe you must finish the game first and after to go back in Star Town to catch it or it needs some kind of trick?
My friend has 58 coins and 24 stars.

You can't catch it until later. When it's time to catch it, you'll know.
