When you complete a request the fan will tell you how many candies you have earned. Choose "Sweet Talk", then "Add 1" three times, then "OK". You can do this after completing your first request as you will have 3 Candy Tickets then, but if you spent some already you will have to either buy more through PSN or play through the game and find some fan damacy's. The damacy's randomly appear, the King will tell you at the beginning of a level if one has appeared. After you roll one up you can exchange it for 3 Candy Tickets by speaking to the Store Clerk on the left of King's head.
