Then part out a tiny section near the crown and place a piggy in it near the part.
Take a section behind that and add it to the first, place a piggy around all towards the ear!
Now add another section to those and place a piggy near the part!
Continue going down the back of the head, adding sections near the part and then towards the ear side. When doing the opposite ponytail try to match the sections so that you end up mirroring each piggy.
At the end place your finishing ponies low so you can put a bike helmet over it if needs be!
