The kids are ready for it...

There are two previous Cinderella stories which are both grotesque to say the least. In one of the versions, written in the 17th century, Cinderella kill her evil step-mother by slamming a lid of a chest on her throat which breaks her neck. In Brothers Grimm version, the step-sisters chop off their feet to fit the glass shoe. When this trickery is uncovered, the little birds that follow Cinderella around, peck the evil stepsisters’ eyes out.
