At Avalor Palace, Elena is reading a letter from Naomi when Armando comes in and announces that Julio has accepted Elena's offer to replace Naomi on the Grand Council. He also informs Elena that Princess Chloe of Norburg is visiting. Elena greets Chloe at the gate. Chloe informs Elena her birthday is coming and wants Elena to plan it in Avalor. Elena asks her about her other friends. Chloe informs Elena she's her only friend. Elena tells her friendship is about giving not taking and agrees to plan her party.
On the day of Chloe's birthday, Elena takes her to the harbor. Elena informs Chloe they are going on an all-day cruise with Mateo, Princess Valentina, and Princess Rebecca much to Chloe's chagrin due to her being prone to seasickness. Chloe asks Princess Rebecca and Princess Val what they do for fun in their kingdoms but she doesn't like their answers. Suddenly, the ship enters the territory of a sea nymph named Maliga, who was banished by her people to the Foglands forever for being cruel and selfish.
Maliga intends to keep them there forever. Chloe offers to stay in exchange for Maliga letting her friends go and the sea nymph agrees. This breaks the curse and the other sea nymphs let Maliga return home. Elena and her friends return home too.
