At the Shopping Center on the lower level where Franca's Cafe is you can find the FUNporium.
You want to purchase Trick Darts for 5000 FUN and take it back to your Room
(Green Elevator Top Option)
Using the console in your room set your Trick Darts up and get ready for fun.
Use the tricks darts over and over and over until you score a Triple 20. Have fun
Using the Visiphone and accessing Personal Shops, the PSO2 Player base has been selling their Dart Boards from anywhere between 700,000-1,000,000 Meseta if you'd rather pay that way instead of saving up FUN.
P.S. If you guys want, my door is always open. I'm in Ship 1, and if you'd like to search for my room, I have Trick Darts set out in my back Balcony. You may use it anytime you wish.
Using the Visiphone (Purple ? terminal) use ARKS Search
