It would be incorrect to say that Sunny eats the rest of her snack. A much more accurate statement would be that she eats a few more bites of her snack and drinks all of the chocolate milk, but either way, she is now full and covered in graham cracker mush. She picks up the napkin and wipes her face, and is still full and covered in graham cracker mush, however she did move some of the mush around a little.
