Riku and his friends escorted Ariel back to the palace. They faced Heartless along the way but they were easy to get rid of. The whole time they were traveling Riku was keeping an eye out for Sora but he wasn't any where to be found.
They entered the thrown room to see a merman with a long white beard sitting on the throne. Arial went up to him. "Hi, daddy," she said.
"Where have you been?" he asked.
"She was running away from those monsters your majesty." Sebastian said.
"And who are they?"
"They're friends I made. They helped me get away from those monsters." Ariel explained.
"We should be going though. I still need to find my friend." Riku said.
"Can I help?" Ariel asked.
"No you cannot! You weren't supposed to leave in the first place!" Sebastian stated.
"But they helped me, the least I can do is help them."
"No, you are supposed to stay in the castle."
"Stop being so crabby. She just wants to help," Riku said. Sebastian looked offended.
"I agree with Sebastian. As long as those monsters are around you should stay here where it's safe."
"But Daddy-"
"I have made my decision." The king stated. Ariel pouted then swam away. "As for you; you're not from around here are you?"
"How could you tell?" Riku asked glancing at Rino.
"Why are you looking at me!" Rino demanded but Riku didn't answer.
"You should know that you are not supposed to meddle in the affairs of other worlds. I thank you for saving my daughter but you should leave."
"Alright." Riku said with a shrug.
"You're going to do as he says?" Rino asked surprised.
"He doesn't want my help with things here. Besides he's the king." Riku said. "If it's alright I would like to look around a bit more to see if my friend is here. I'll leave once I finish looking."
"Very well but be quick about it."
Riku nodded and left the thrown room.
"So where are we going to look?" Rino asked.
"Where we haven't yet." Riku stated.
They looked around and found their way to a wrecked ship. A shark was swimming around and they decided to leave that area alone for now. Riku started messing around at a point and got a ride on a dolphin.
"Are you serious! If that king finds you're messing around we could get into trouble!" Rino said trying to keep up with the dolphin. Riku let go of the dolphine and Rino swam past him but stopped quickly. Rino looked at Riku to see he was staring seriously at something. Rino looked to see the king swimming towards them. "I told you," Rino hissed in a hushed voice.
"Please, I need your help," the king said when he reached them. Rino, Donald and Goofy looked at him surprised.
"Help with what?" Riku asked crossing his arms.
"Ursala, the sea witch, has taken Ariel."
"I thought I wasn't supposed to meddle."
"I know but I can't get her back myself."
"Alright. We'll get her back, don't worry," Riku said with a grin.
They went back to the shipwreck because it was the one area they didn't search. Sebastian was sent with them even though Riku didn't understand why. They went into the shipwreck to see if there was a hidden passageway in there.
"Riku, I don't think this is a good idea." Rino said staring out the window of the ship.
"Why?"
Rino moved away from the window just as the shark bashed into it. "That's why!" The shark managed to get it's self stuck and was thrashing around trying to get loose.
"That's helpful. Now we don't have to worry about it chasing us. Come on let's go," Riku said.
The swam around the area and found a rock with a picture on it. Sebastian managed to press a hidden switch that opened the way to Ursala's hideout.
They made their way through into a cave that looked like a giant mouth. At the bottom were a bunch of strange creatures.
"What are those?" Rino wondered.
They continued on to find Ariel and Ursals further in. Ursala was trying to talk Ariel into doing something.
"Don't trust her, Ariel." Riku said as he entered.
"What? How did you get here?" Ursala demanded.
"We followed the path how else?" Riku asked as if it were a stupid question.
Ursala looked mad. "How dare you come in here unannounced?"
"Ariel, she's bad news. We have out of here."
"I don't think so. Ariel's not going anywhere. She's staying here with me!"
Ariel looked at Ursala and started to swim away but Ursala's eels wrapped around her and trapped her.
Riku and the others got ready to fight. "Let her go!"
"As if," Ursala said and tossed a bottle into the cauldron thing making a whole bunch of sparks and smoke.
"Rino, can you get Ariel? We'll deal with the witch."
"Sure, leave it to me. Hey wait why-?" before Rino could finish his sentence Riku was gone. He disappeared into the smoke to attack Ursala. Donald and Goofy were helping him out. They managed to beat her back after a while.
"You'll pay for this." Ursala said before swimming away.
"Most bad guys say that," Riku mumbled then turned to look for Rino and Ariel. Rino was swimming back into the area. "Where's Ariel?"
"With her dad. I took her back while you were fighting."
"Good, then our business is done here." Riku said.
"Let's get going then," Rino said slightly happily.
