This was really easy. It's just 4 ponytails closer together to make it look like one big one. You need to divide the hair in four sections. I parted each of mine like a triangle so they all came together in the middle.
Make your way around the head adding your elastics. Do all four piggies like that. Then I just curled her hair. I added a bow just on the top one but you could add it on the 2 sides instead, if you like it better. front view:
