I Need to get my Girlfriend something for Christmas!?

Okay, so a week ago I bought her these Ugg Boots she's been wanting, but then she found them and I just said "Well here's your early Christmas gift!" lol, and now I need to buy her something else, but we made a Deal that our Christmas gifts will only go up tp $50, since we already bought each other something ( she got me the new CoD game) So,as of now I am at a stand still as to what to get her. She is my age, 16, she loves softball and animals. We've been going out for a year and 9 months now... Any suggestions?
