His brothers left home and, wanting to be with them, the boy followed until they blinded and abandoned him. After his sight was magically restored, he reunites with his brothers, who make him their servant. Then there's a competition to win a princess bride and the boy wins with the help of the enchanted horse.

The Carnation Prince

Three sisters tried catching a carnation. The youngest succeeded. She put the flower away and later found that it'd turned into a prince, whom she accidently enchanted. To disenchant him, she had to travel until she wore out an iron dress. She happened upon the sun, moon, and the birthing person of all animals on her odyssey, and each gifted her an item. After feeding all of her limbs to a bird, she arrived at her paramour's home and they were happily reunited and married on the spot.
