(A modern day Cinderella) the old hag slips her tiny foot into the slipper, and it fits! Now the prince has to carry out his promise (and marry her). / The two dwarves (who have been carrying the slipper and cushion around) mutter that she can’t possibly be the genuine article.

This is “dagger” (32a) but with an extra stroke.
