What are good birthday presents for a nine year old?

A nine year old girl is pretty easy to find a present for. You can get her makeup ( like a cool lip stick thing ) or shirts/posters of just beiber or high school musical or anyone she is into. Another idea is just a gift card for Walmart. Also coloring books, candy, 'friend chat' book's or if she has a Nintendo or wii get her games for that.
