you dont need to. its a distraction to talk to the guy in internet cafe.
The guy who can't stop playing his game in the Internet cafe. Take a green balloon to the little boy in the country side and he will float off. Then return to the cafe and talk to the man about the tickets.
Once you have given a green balloon to the kid in the Countryside (not what you expected), the man at the Internet Cafe will talk to you. Return his tickets and he will give you one to use.
Talk to the Curator in the Web Browser cafe, then meet her in the expressionism wing at the museum to get your island Medallion.
First you have to go to the clown shop and get a balloon. After that, go to the country side and give the boy that's crying the balloon. Then you go to the internet cafe and talk to him.
you have to talk to the mimes and they will motion you to go to the jazz cafe.
Once you take a green balloon from the Clown Store to the Countryside, there is definitely news. Return to the Internet Cafe. The guy outside will not let you pass without telling you there is news. The guy inside will have stopped playing games and you can talk to him. (see related question)
you go back on counterfeit island
They don't talk back. When you show them the photo of the thief, they will mime "music", suggesting that the thief is at the All That Jazz cafe. (You can look there first, but he's not there yet.)
Talk to the curator as you exit inside the Web Browser Cafe. Return to the Museum to receive the Island Medallion and discover the secret of the Museum Fantastique.
After Balloon Boy goes flying, go to the Web Browser internet cafe and talk to the guy next to the TV. He is the owner of the tickets and was too busy playing games to pay attention to you (the news story distracted him).
You don't. They are MIMES : they never talk when they are performing. If you show them the photo of the thief, they pantomime "music", which suggests you look in the All That Jazz cafe.
