The Vow to Be Brother and Sister

Ronja thinks about what will happen to her if it starts snowing again while she is stuck. Meanwhile the Rumphobs have fashioned her foot into a swing for their baby's cradle to rock him to sleep as she struggles, wiggling her foot. A harpy spots Ronja and starts taunting and threatening her before attempting to free her in order to make Ronja her slave. The harpy tries to fly away with her in vain but promises to return the following day with her sisters to help her.
