Your wicked sisters, Prince Ursula and Princess Glorinda, are both jealous of you, both for the regular reasons and for the simple one that your father, King Gustav, has promised the handsome and rich Prince Loren the hand of whichever of you the Prince most favors.
You, like your sisters, are quite attractive, but unlike your sisters, the fairies that came to your christening blessed you with glorious red hair down to your waist, not to mention two amazing breasts, both as round and ripe as honeydew melons. Ursula and Glorinda, meanwhile, have apples and pomegranates respectively.
Yet they conspire with the wicked fairy Hagabertha, who has cursed every princess of your house except the current generation, and that only due to being preventatively locked in the dungeon with a fairy-proof iron lock when she showed up for your christening, aged evil fairies not having amazingly good eyesight, and your parents having had the forethought to decorate a dungeon cell as an attractive waiting room, the better to lure her in.
But Ursula and Glorinda count on the fairy being grateful for her rescue, and moreover, wanting to take her revenge on the one princess who did not conspire to free her.
"Give us her glorious hair and her amazing breasts!" Glorinda cries as they stand in the hall before you, the ancient and evil fairy supported between them.
"Yes," agrees Ursula, "and leave her with nothing. I'd like the breasts, particularly."
"I want the breasts," Glorinda counters. "After all, this was my plot."
"Yes," says Ursula, "but it wouldn't have worked if it hadn't been for me stealing the key."
The old fairy cackled. "Girls, there is hardly any reason to fight. There seems plenty to go around." She leers at your cleavage. "Plenty, indeed. You can certainly share."
She waves her black and thorny wand, and you feel your hair leap off your head, and your breasts leap from your chest as well, launching for your sisters as the wicked fairy Hagabertha summons a chariot borne by geriatric griffins and flies away cackling, and you begin to weep, finding yourself as breastless as a boy, and bald as a baby.
But then you note where your hair and breasts have gone. Princess Ursula and Princess Glorinda both have one of your magnificent breasts attached between their own smaller ones, and your magnificent red hair has divided and attached to their faces, giving them huge red beards like dwarves or barbarian warriors. Which look even worse because Ursula has brown hair upon her head, while Glorinda is blonde.
You realize then that, despite the fairies curse, you're still the most beautiful, since most princes prefer bald flat-chested girls to triple-breasted bearded ladies!
