Under the Sea

The four stopped at the next world. "Ok, guys. Prepare for landing." "Uh, Donald? There's nowhere to land." "Just leave it to me!"

The group appeared in the sea.

Niji looked at herself and laughed. She started swimming around happily. "I always pretended to be a mermaid back at home!" She twirled with ease. Riku chuckled at her, "you sure to be having fun. Mind helping me out?" She looked at him and giggled. "Having trouble, Riku? I thought you were better than that." He tried to swim at her, but flipped over instead. She started laughing.

A scream was heard.

The duo looked over to see a crab swimming behind a mermaid. "Relax, Sebastian. They don't look like one of them. Right, Flounder?" "I don't know. There's something weird about them." The mermaid swam around Niji. "They do seem... a little different. Where are you from?" "We're actually from the other side of the world. I'm Princess Niji, nice to meet you. These are my friends: Donald, Goofy, and my best friend Riku. I guess I'm more used to swimming in these types of waters."

"Oh, I see. Sebastian can show your friends how we swim around here!" Niji smiled at her. "Thanks! Who are you?" "My name's Ariel. I'm a princess, too." "Wow! It's really nice to meet you! Oh, um, have you seen a keyhole?" Ariel started to think. "No. I don't think so. Sorry." "It's alright. Would you be kind enough to help us find it?" "Sure. It shouldn't be too hard to find." "Niji!" The girls turned to Riku then looked to what he was pointing at. Heartless were coming at them. The trio hid while the group took them all out.

"Those creatures chased us here." "Oh, no! Those monsters might be heading for the palace, too!" "We'd better head back right away!" "But, wh-what if we run into more on our way back?" Niji swam over to them. "We'll protect you! We've been fighting them for years." Ariel smiled at her. "Thanks Niji. Let's go!"

The group swam off towards the palace. They entered and the Heartless behind them were taken out by a ray of light.

"That was too close. As long as I have my trident, I will not tolerate those creatures inside this palace." "Daddy?" "Oh, Ariel! When will you listen? It's dangerous out there! Strange creatures lurk outside." Sebastian cleared his throat. "Behold. You swim before the ruler of the seas: His Majesty, King Triton!" "And who are they?" "They helped us fight off those creatures." "They don't look familiar." Niji bowed a bit. "I'm Princess Niji. It's nice to meet you. We came here to seal the Keyhole, to protect the ocean from those awful ceatures." Triton stared at Niji then figured it out. "You're a princess of heart and the key bearer?" "Um, yes." "I see."

Riku swam up a bit, "King Triton. A sea witch by the name of Ursula is the one responsible for those creatures here." "Ursula?" "She's in league with others who control them. We have to stop her from finding the Keyhole, or the world will be lost." King Triton nodded. "I understand. Please take care of her and close that Keyhole." The group nodded. "Daddy? May I go, too? They'll need help finding their way around here." He sighed, "alright. You all better keep her safe." They nodded once again.

The group went off to find Ursula's lair. Once they found the way, they went all the way inside to confront her.

"It's over, Ursula!" Ursula turned to the group. "Aha! Riku, you brought me the girl? You are such an angelfish." Riku glared at her and summoned his weapon. "We're here to put an end to you!" "Why you--" Ursula started using her magic. The group took her out along with her eels. "Yes!" Niji hugged Riku, "we got her!" He chuckled and rubbed her head. "We sure did."

They went back to the palace.

"Thank you for saving our world. I'll show you the Keyhole." King Triton got up and swam out. The group followed after him. They entered Ariel's Grotto and he used his trident to reveal the Keyhole. Niji summoned her Keyblade and locked it up. She looked over at Ariel. "We're from another world... sorry for lying to you." "Oh, it's ok. If you can travel to other worlds, maybe I can too. So many places I want to see. I know I'll get there someday." Ariel smiled at her. "Oh no you won't, Ariel. You will stay in our world. You wouldn't be able to roam around them without water." "But daddy--" "I'm sorry, Ariel." He left them be.

Niji looked over at her friends. They swam out of there.
