Firstly, the bragging father whose big mouth leads to his daughter being locked in a tower and forced to spin straw into gold upon threat of death if she fails. Spineless woodcutters are bad enough (leaving Hansel and Gretel to die in the forest), but dad as virtual pimp, OMG.
Next we have the “little man” whose name we do not know, but who gets a necklace (something close to the girls heart and bosom), ring (symbolic marriage vow) and finally promise of her firstborn child (how personal is that?).
With firstborn kid deals we’re in the realm of Rapunzel, but at least the ravenous-for-rocket preggers mom is above the age of consent when she makes the deal to trade her unborn child for arugula (alas, poor Rapunzel ends up locked in a tower over a salad). With Rumpelstiltskin the unnamed girl (and this is interesting to me, after so much is ultimately made of the name of the little man) comes into unsavory contact in the tower that is not meant to protect her purity, but keep her from leaving if she doesn’t give up the gold.
