Last April 4, Flyff PH launched a summer event called Children's week. It is a three-part quest and the good thing about this is that this is repeatable. A player may get the rare item which is a cute kitty buff pet.

When i have the chance to go online I will try to do this quest so i can tell more about it.
Have you done this quest already? What items did you get?
