Well if you really want to do spooky or at least mock spooky, how about just Myfanwy's crest in the middle of the straw and her friend to one side - Beaks 2.
Spookier would be grain on the left hand side, her friend in the middle and her crest and beak just visible on the right - aimed toward the grain - Beaks 3D.
I always see the opening off Airplane when I think of Jaws.
