Where are the tickets to the Underground Tour on Counterfeit Island?

Go to Downtown and there are two rubbish cans at the Underground Tour entrance. Click on the right one and take out all of the trash

• there are two tickets there.

They belong to the man in the internet Cafe, but he will give you one if you can get his attention. (Take a green balloon from the Clown Store and go to the Countryside, and you will see some news on the cafe TV.)
