I have had one since 2011, and when my nephew (7) saw mine he said he wanted one in blue.  But since it was gifted to me I didn't know where to find it.  On amazon, just browsing (not looking to purchase) I saw it and thought he had to have it.  When he got it this 2013 (9) he called me immediately and was screaming "OH MY GOD, YOU DIDN'T FORGET, THANK YOU THANK YOU THANK YOU, I LOVE YOU SO MUCH".  That made me feel good.
