The furby uses 4 AA batteries to power it.  I don't ship electronics with batteries.  The battery terminals are clean.  I tested it and the eyes come on.  The sound is good.  I touched the belly and it reacted.  The tongue works.  The top of the head responded too.  The ears moved as well.  Something in it rattles or sounds loose, but it doesn't seem to effect anything on its function.  The fur and the ears look good.
