Batteries?

According to Rose, Batteries are edible. They are cute little cylindrical shape with fancy markings on them, usually packed in 4 like many candies so she has some points in that! However the hard part is when she brings you a battery and wants you to open it for her so that she can eat it. This is the time when batteries disappear and dogs come out and cats meow or any other thing that can take her mind off the batteries happens.
