A few days after her father's funeral, Ariel gets a note from her sisters in Mermista in a bottle washed ashore on the beach. "Dearest sister," reads Ariel, "Aquata, Andrina, Arista, Attina, Adella, and Alana here. Some outsiders, pirates, have been spotted on the outskirts of the city by our merman and mermaid scouts. We need help, backup, fast. I know we don't normally ask humans for things, but we could really use the help of your army and navy. Yours truly, your sisters who love you oh so dearly."

Ariel then goes inside and brings the request to Eric and his generals and captains in a meeting. "Men," says Ariel, "the merpeople are under attack and need the help of your ships and soldiers. Pirates are trying to take over the new mermaid kingdom of Mermista and they're basiscally defenseless."

"Of course, we'll help princess," responds the Captain. "How many ships and men?"

"Ten ships, five thousand to ten thousand men," responds Ariel. Eric then butts in.

"I think we should double it, my love," responds Eric.

"You heard him, Eric knows what is best."

Later that same day, the twenty ships and ten thousand men are sent out to protect Mermista and its residents from the pirates. Ariel, taking back to her mermaid form with Ursula's necklace, leads the way with Eric's ship right behind her.

Meanwhile in Marista, the mermaids and mermen are doing their best to ward off the pirates but to no avail. Before they know it, Attina and Alana, the first two heirs to the throne are speared and killed. This causes the guards to sneak Adella, Aquata, Arista, and Andrina out of the city. They somehow, by some miracle, do this without a problem.

A few moments later, Eric and his men and Ariel arrive at the city of Mermista and help out in the fight against the pirates. Meanwhile, a messenger tells Ariel the bad news. "Your sisters, Attina and Alana perished before you arrived. Speared to death." Ariel breaks down in tears.

"How? How could this have happened? We're too late. Where are the others?"

"Your other sisters are safe, don't worry," responds the messenger. "The guards got them out safely."

"Wel, that puts my mind at a little bit of ease," responds Ariel. "Can you take me to them?" The messenger nods and swims Ariel out under the darkness of the ships and to the secret location where her sisters are hiding out. There, Ariel happily embraces them in a hug, but is greeted only with frowns and tears. They're still mourning the loss of the two sisters.

"I know my sisters, I'm mourning them too," responds Ariel, "but at the same time, I'm glad you're all safe."

"True," respond the sisters.

"But, but that means as soon as this is over, Ariel, that means I'm to be queen," responds Adella. "I'm third in line after all, or, well, was."

"Well," responds Ariel, "you'll be a great ruler, big sis."

"I sure hope so," sighs Adella. She then swims off into a corner of the safe cave and begins to cry.

Ariel then tries to swim back out of the cave but is stopped by the guard's crossing spears. "Not with pirates out yonder, princess," responds the guard. "We're sorry."

"But, but my husband needs me," responds Ariel bursting into tears.

"He has his men, he's fine," responds the guard. "You'll be reunited with him soon enough. We promise." Ariel thanks them and returns to the inside of the cave and sits there and pouts. All she can do now is hope that Eric and his men can finish off the pirates soon.

Several days later, maybe about fifteen, the pirates are soon fended off and retreat back to where they came from after throwing their dead into the sea. Eric, on the other hand, takes his dead men home and buries them in a heroes burial along the beach. Ariel and her sisters soon leave the cave and swim towards Eric's kingdom escorted by the merman guard. There, Ariel gives each sisters a specialized piece of Ursula's necklace to wear just in case they ever need to come to the surface world for safe harbor. Ariel then sahres a tear filled hug with her sisters.

"Goodbye Queen Adella, and my other sisters, Aquata, Arista, Andrina."

"And goodbye dearest Ariel," they say before letting go of her and being escorted back to Mermista where later that same day, Adella takes the throne as the first queen of Mermista. All the same, Ariel can't help but feel with a new ruler on the throne, there is surely more trouble to come her family's way and that's what scares her most.
