1. Firstly go to Counterfeit Island via the blimp if you are not there. Go to the Web Browser Internet Cafe where you will see a big blue book on the table, if you go a little left.
2. Click on it and a loose page with some French vocabulary will fall from it. Go out and go right to the Moldy Baguette Inn. Go up and on one of the windowsills you will find a piece of paper. Pick it up and jump down.
3. Go to the Boobo’s Clown Store to your right. Click on the green balloon or else it won’t work. Go outside the store and turn right, into the countryside. You will spot a little boy crying and his mom has a red balloon. Actually he wanted a green balloon, but red.
4. Give the balloon to him. He will start floating in the air. Thus he was nicknamed ‘Balloon Boy’. Go to downtown and turn left until you reach a bundle of trash cans. Click on the open one. You have to search through them to find the Underground Tunnel Tour tickets.
5. Go to the Main Street and make your way to the Web Browser Internet Cafe. Go right until you see a tourist guy. Apply the Underground Tunnel Tour tickets on him. He’ll thank you and offer one for you as well!
6. Go downtown to the underground tour leaving the cafe. Use the ticket and just walk through. Stop when you see some skulls. Jump up on the light to secure the next piece of paper.
Go down to exit through the docks.
