Don Pianta's office:
After chapter 2 you will have to talk to Don Pianta to get a blimp
ticket. Without my help, you would have to pay all your coins for this
information. All you have to do is go to the item shop on the west side
of Rougeport (the one with the Boo in it). Buy a dried shroom (2 coins)
and a dizzy dial (12 coins) IN THAT ORDER!! If you did it correctly the
Boo will ask you what the color of your mustache is. You must answer
"yellow". Then she will tell you that she asked the wrong question and
asks what your favorite color is. Once again, answer "yellow". Then she
will say that you know the password and will let you go through a door
on the left side of the room. Go through it and up the stairs to Don
Pianta's office
