Is River still in the Coke box?

Yep.  How do I know?  Check out the white tuft of fur sticking out of the box's cut-out handle.

River was in the Coke box first, then Simon decided to join the party.  Now the poor Coke box is all sorts of wonky looking and I'm questioning River's ability to breathe in there if I can't see her face.

With a little helping hand, I've secured an airway for her.  Simon is not as small as he thinks he is (even if he is about 90% bunny fluff).
