Who eats all the plants, then, Will?!

The most severely nibbled plant on the windowsill.
Attacked on daily basis!

Plant he has barely touched as yet . . . 

Plant on other windowsill so far ignored by Will.

Middle plant on windowsill showing signs of
nibbling already!!

Mr. Innocent himself!!!!
"What me, eat plants? Never!!! How could you
think such a thing"?!!!

Of the two, which one would you be most likely to
suspect, then? Got it in one!!!!
