This item is created by clicking special items such as Bristlebane's Party Generator. Each click grants a stack of 20 pies that can be thrown at other players for fun.
When thrown they have a round, pie graphic befitting the item name. The original animation looked like a fast moving rock that was difficult to see. SOE updated this with a better graphic and it is now slow enough to SEE. The target will respond with a "stagger" animation when hit (if they are standing). Only PCs can be hit. You can also stockpile stacks of pies for future mischief. :) Sadly, they cannot be traded.
A stack of these are also one of the final rewards for completing all 16 of the Deity Favors quests for the EQ 10th Anniversary.
[EDIT: Updated with details of the new animation/graphics.]
