Go to the Rosequeen Shop in Pot au Feu City then go to the shop owner. This trick might require some patience, but is well worth it. Buy some Change-ups or any cheap item in the shop, then do the survey. Do any of the four questions and sell the item back. Keep doing this until the girl asks "If you had one wish, what would it be?". Once you have that, you can get any of the triple effects.
