BOYFRIEND BDAY GIFT IDEAS?!?

My bf is going to be 13, and im still 12.. I wanna get him something, but not something to big, because I dont wanna freak him out or anything.. He has had this hat for like FOREVER, ever since he was in 2nd grade.. And he is like obssesed with firefighters since his dad is one, so i was thinking that i could get him a new hat that had our towns fireman thing on it or something? i dont know.. I just want something sweet, nothing like "Show him your ****, or give him your v card" I am FAR to young for that.. Any ideas?? thanks :)
