Once they returned Pinocchio to the man Riku and the others left Monstro. Rino had apologized for losing Sora and Promised to help find him. Rude left to go back to the Coliseum to see if Sora might have gone back there while Rino went with Riku and the others to look for Sora. Riku was sad for a bit but managed to cheer up.

"Hey Sora probably left to keep looking for Kairi. When we see him I can tell him she's safe," Riku said with a grin.

"So that's more reason to find him then!" Rino said glad to see Riku was in a better mood.

"Yeah. On to the next world!" Riku said.

"When did you stop driving?" Donald asked.

"Oh come on you didn't even want me to drive in the first place." Riku pointed out and Donald huffed.

Donald got them to the next world which was all water. "How can we go there? I can't breathe under water."

"Leave that to me. Let's go!"

"Wait-" before Riku could say anything else they were in the water. Riku held his breath and tried to swim up when he realized that he was moving differently. He looked down to see his lower half had become a silvery tail for swimming. "Woah," Riku said as he looked at the tail.

"Gyaaa! Where's my suit. Where's my shirt?" Rino asked. Riku looked over to see Rino had also gotten a fish like tail but it was red. Rino was also trying to cover his torso with his arms.

"Do you have a phobia of skin or something?" Riku asked.

"No, I just want to know why my shirt is gone!" Rino stated.

"Just deal with it. I'm sure you'll have your shirt back when we leave." Riku said. He was already adjusting to his new body.

Rino sighed and was slowly sinking. "I don't think we're going to find Sora here so maybe I could just go wait on the ship.

"If you want to turkey," Riku said as he swam over to Donald and Goofy. Goofy had become a turtle and Donald looked like an octopus that was half duck.

"Get it right for once. The group is known as Terks." Rino said. He hit the sea floor and realized he had been sinking. He swam awkwardly for a moment as he went to join the others.

"Help!" someone yelled. They all turned to see a yellow and blue fish swimming their way. The fish saw them and went up to them. "Please you have to help! My friend, she's being attacked by monsters!"

"Monsters?" Rino muttered.

"Where?" Riku asked and pulled out his keyblade. The fish started swimming and they all followed it. The fish lead them to a big area where a mermaid with red hair was being chased around by heartless. As they approached the heartless managed to corner her.

"Ariel!" the fish yelled and was about to swim over to her.

"Hey, don't go in there you'll just get hurt." Rino said and grabbed the fish as Riku and Goofy swam over to help. Donald was already casting magic to beat back the Heartless from the mermaid. Once she was no longer cornered she did her best to help fight off the strange jellyfish-like Heartless.

They managed to defeat the Heartless quickly and Riku looked around to make sure there weren't more of them. "Oh thank you for helping me." The mermaid said.

Riku turned to her and smile slightly. "No problem."

"I'm Ariel, and that's Flounder." She said and gestured to the fish that got loose from Rino's arms. "You're not from around here are you?" she asked swimming around Riku.

"No. We're here because we're trying to find somebody." Riku explained.

"Ariel!" A voice called. Everyone looked over to see a crab swimming their way. "Ariel, you can't just go running off like that. You could get into danger especially with those monsters lurking about."

"Sebastian, I'm just fine. Look, these people even helped me get away from those monsters," Ariel said and gestured to Riku and his friends.

"And who might you be?" Sebastian demanded from Riku. Everyone introduced themselves except Rino who was forgotten in the background and skipped over.

"Well thank you for helping Ariel but we really should be getting back now. The king will be worried if you don't return soon." Sebastian said.

"Okay. Riku, do you think you can come with us? Just incase those creatures attack again?" Ariel asked.

"Sure, we can keep an eye out for our friend while we're at it," Riku said turning to look at Donald and Goofy who nodded in agreement.
