Aztec Curse?

When I was young, I collected all kinds of weird stuff.  This little guy is a left-over from those days.  I have no idea what it is or where it came from .  He sure is creepy though.  Maybe he's an ancient Aztec idol and now that I've taken his picture I'll be cursed forever.  

What the hell is he holding in his right hand?
