Looney Puzzler!

While looking at Looney Tunes comic covers to perhaps advance things a bit, a problem arose. Now, I have a fairly good familiarity with the characters, but I'm stumped.

Take a look at this:

or this:

and see if you can figure out who or what are casting the shadows seen in the window in the upper left.

And yes, I've already checked with the World's Looniest Expert.. er, the the World Expert on Looney Tunes, michaelmink and he's not sure either.
