four arm character rigg and ready to go
I don't know why that happened if anyone can help. that would be super cool
The rotation of the last bone of the tail is wrong. I recommend CG Cookies intro to rigging, this rig still needs a lot of work for it to be useable, since placing bones is a tiny part of what rigging is.
I'm sure you'll make this character trully unbelievable after some work ;)

Awesome rig, though there are some weird deforms on the tail.
