Hungry or Confused

I swear, sometimes I'm most confused by Mabel Lou's behavior.  I often think that maybe she is confused about what species she is.

Here she is fishing for krill:

 And here she is again, digging for ants:

 

And yet again, chewing her cud:

  Does Mabel Lou think she is a whale? An anteater? A cow??? Or maybe she's just hungry!
