What should i get my friend for her birthday?

ok, well my friend is going to be 17 in july. i want to get her a bunh of random things because we r really random. So far all i have is goldfish (like the food, she loves to steal them from me) and silly string (like the kind that u spray out of a can) im also planning on getting her balloons for her too. What else should i get her? she plays clarinet in band, loves to draw, she is my "grandma" (therortically) and we are apart of a fake family that is called the chub chubs :P Please help me get some awesome ideas :)
