I recall BenDover saying that as it presently stands , the item forger can only create hair for the head region , and if you haven't noticed yet , it isn't exactly 100%, meaning , that attempting new things such as something as silly as a monkey tail , would be a terrible step to take.
We should let the item forger team perfect the current bugs found with the hair items we have right now , as well as the up coming hair items , before moving onto something new , which would create more problems , bugs , frustration.
