seems alot of people are posting what they are getting but not any tips on how to do the events. I hope this helps a little and please correct me where im wrong.
Hope this can help some people out. and keep in mind this is still just a working hypothosis.
Facts Tips:
1. you can use fruite as sweets. As far as i can find so far the cheepest fruite to buy at this moment would be sar. Oranges. Where to buy dependes who owns the Satutabaruta region. And i would bet 1 mil gil that it would be Windurst, so head over to windy and buy some oranges. (if Windurst does control the Sarutabaruta region on ur server, talk to Baehu-Faehu (a little taru) near the gate in Windurst waters across from the guy that gives you signet at G-5)

Hypothosis Tips: (these are not for sure but pretty sure)
1. Items drops are randome. What you hand the person does not seem to matter at all. So dont wast money on thoes +1 items or pies people are shouting for in order to get +1 drops. This doesnt seem to be the case.
Try This For Success:
Ok this is a work in progress but it comes from following around a level 75 JP RDM on my server that had two of the +1 itmes. I followed him around for 2 hours and this is what he did. While i was following him i recived two drops myself useing only oranges so this seems to work. Go to windy since most likely thats where the oranges NPC will be. NPC's you can trade the oranges to are in windurst waters and windurst woods. Find all the NPC's dresed as MOB's (monsters) and create a rout, a rotation making sure to hit them all then start over again at the first one. Trade one item to one of the NPC's. If you turn into a MOB (get a costume) then you go to the next one.. once you get there (or right away if you want, but i like to trot around a bit as a mob) hit the + button on ur numberic keypad twise, select the orange costume icon with your arrow keys and hit enter to erase the costume mode and turn back into yourself. Then trade the orange (or whatever sweet) to the next npc in costume. Keep doing this in rotation over and over till you have all the items you wish to recieve. Every now and then switching areas seems to help a bit. So to be safe (eventhough it mgiht not matter) switch between windy waters and woods. Its a long and grueling process. but with the oranges at a cheep price it shouldnt be to expensive concidering the fun items you get, u just got to put in the time.
