Meaningful birthday present.

Cry Baby • There is only room for one cry baby around here.
I'm into giving really meaningful/special birthday gifts, but I'm having a hard time deciding what to get my bf this year. This is his 6th birthday I'll be spending with him and I don't know if I can outdo myself from past presents. I want to chose something he'll really love! He likes drawing, skateboarding, music, and collects crystals. Do any of you ladies have any ideas?
