Chapter 1

The alarm went off. Kurt groaned. It was 9 am. Why didn't he forget to turn it off in the holidays? He rubbed his eyes, got up and went to his closet. Blaine was still sleeping in his bed, snoring lightly. Kurt smiled faintly. Even if someone blew up the whole place, he still wouldn't wake up. After he dressed himself with one of his fabulous outfits, his phone beeped. Kurt unlocked it and read the new text.

Mercedes: mornin' white boy! u up to a shopping spree with us girlz? xxx

Kurt smiled to himself. Mercedes knew him to well. He would never say no to an offer like that.

Kurt: Why are you even asking :P xxx

Mercedes: Dunno xD Let's meet at the lobby in five xxx

Kurt grimaced. Now, he didn't even have time to do his moisturizing routine. 'Screw it', he thought to himself. He could still do it in the evening. So, he just sprayed his hair for one second, left a note on Blaine's dresser and left.

Turned out the malls in Venice were not as spectacular as everyone thought. Even though the clothes weren't special, they were pretty expensive, so Kurt and the girls ended up buying nothing but souvenirs. However, Kurt wasn't that disappointed. He was inspired by the flair of Florida and its relaxed atmosphere, and even made some sketches of possible clothes he will design one day. If he wasn't obsessed with NY, he would definitely choose a college in Florida. "Come on, Kurt, stop staring at your notebook and get moving! We got to check out that boutique over here!", Rachel interrupted his thoughts. Kurt lifted his head. The girls were already in a small boutique and Mercedes dragged Rachel to one of their stacks of skirts. He closed his small notebook, put it back into his pocket and got up from the seat. At the left of him, a small, damaged water fountain was sprinkling water in every direction. Kurt frowned. That water could totally ruin his outfit and his perfectly coiffed hair! Suddenly, the fountain made a weird noise and a large beam of water was about to splash him. Kurt threw his hands up to protect himself from the water and waited for the impact. But it never came. The boy slowly opened his eyes. And gaped when he saw a frozen beam of water. Kurt tentatively touched the ice with his fingertips. It was frozen solid. "How the hell is this possible?", he murmured, stunned. "Kurt? Where are you? We need your advice!", Tina called out from the boutique. Kurt looked around. Luckily, nobody witnessed that whole thing, so he could just pretend all this never happened, right? "I'm coming!", he shouted and quickly went to his friends without looking back.

Blaine opened his eyes and yawned. He thought he heard Kurt leaving while he was asleep and quickly checked the other boy's bed. It was indeed empty. He noticed the note on his dresser and read it.

Morning, sleepyhead! The girls and I are hitting the malls in Venice, don't wait for me with breakfast…or with lunch. I honestly don't know when we're going to be back…Anyway, have a nice day!

XOXO Kurt

Blaine grinned. He knew Kurt. When he hit the mall, he wouldn't be back until sunset. Blaine put on his slippers and went to the bathroom to wash his face. When he turned on the faucet, he started thinking. What was he going to do until Kurt returned? Maybe play beach volleyball with the guys again? Or some video games with Artie and Mike? Blaine was about to turn off the faucet when he felt a weird sensation in his legs. One second later, he fell to the floor. Blaine frowned. What was that? He looked down his legs…and paled. Right there, where his legs were supposed to be, was a long, mint green fishtail. All Blaine could do was stare. How the hell was that possible? He continued laying on the floor like that for a while but then, he heard a knock on his door. "Blaine? It's Mike. You didn't answer your texts or phone calls, so I came here to check on you. You're up for a gaming day with me and Artie?", he heard Mike say. Blaine panicked. What was he going to do now? "Yes, I'm coming, wait a sec. I'm naked", he lied. Desperately, he took a towel and dried himself. All of a sudden, his body was tingling and then, his legs were back again. Blaine gaped at his legs as if they belonged to another person. The heck? He glanced from the faucet back to his legs and to the faucet again. Water! Some seconds after he had touched water, he turned into a male version of Ariel. But why? "Blaine? Everything okay in there?", Mike asked from outside, sounding concerned. Blaine cursed under his breath. Mike was still there, he totally forgot about him! He didn't want the others to grow suspicious, so he had to act like he always did. Well, almost. As long as he didn't touch water, he would be fine. Or so he hoped. Blaine quickly got up, brushed nonexistent glint from his pants and went out the door.

"Oh my gosh! Do you see that surf instructor? He is totally hot!", Tina gushed. Mercedes and Rachel turned their heads. "I totally have to agree. His abs look great", Mercedes smirked. "And his gold hair! Like an angel!", Rachel swooned over the blonde guy. Kurt rolled his eyes. If Santana was there, she would go Lima Heights Adjacent on the three girl's asses to bring them to terms. Unfortunately, Brittany and the Latina stayed at the mall to drink protein smoothies as a dinner-substitute, so he had to do that (of course not by kicking his friend's asses). "Guys! Don't even think about flirting! You are all in relationships, remember?", he said, but was ignored. The three girls headed down the long pier to the guy like their lives depended on it. Kurt reluctantly followed them. The farther he went out the pier, the darker the water became. The water had to be really deep out there, Kurt thought. At the end of the pier, the guy was about to show the girls some surfboards. "Kurt!", Rachel squealed delightedly. "Brendan wants to show us how to surf. Isn't he gorgeous?", she gushed. Once again, Kurt rolled his eyes. "Well, it's his job. But yeah, that's great!", he said sarcastically. Tina and Mercedes, oblivious to his lack of interest, took him by the arms. "Come, join us! That will be fun!", Tina said excitedly. Kurt shook his head. "You know exactly what sea water does to my skin. Or my hair. Have fun without me". The three girls pouted. "Only this time! Pretty, pretty please?" Kurt sighed deeply. He knew his friends would never give up until he joined. So, he just nodded, albeit begrudgingly. Everyone took a surfboard from the stack, then the instructor showed them how to put their foot into the surf rope, a leash attached to the surfboard. Kurt sighed. Instead of that nonsense, he could lie on the beach and read the latest Vogue. "Okay, that was great guys! How about we go to the beach now and then we do some easy exercises for your muscles?", Brendan suggested. Mercedes looked disappointed. "We are not going to surf now?", she asked. Brendan laughed, then shook his head. "I'm sorry to disappoint you, but you think I will let you surf with no experience? That's not that easy. Let's go!" The girls got their feet out of their leashes, but Kurt was too busy checking the updates of on his phone. "Kurt are you coming?", Rachel called out. Kurt, who was still sitting on the floor, waved her off without looking away from his phone. "Yes, but not now. My ankle is still tied to the surfboard. You can go ahead, I will join you later...", he mumbled distractedly. Rachel nodded and ran to the others who were already on the beach. Kurt finished reading the latest post, then he locked his phone. 'I hope this won't take long', he thought to himself. He laid his phone next to him and got up. The sight in front of him was picturesque: only the sea, which was shining in the deepest blue, and the bright sky. Maybe he could use that contrast for his next design. He took a step towards the edge, not realizing his ankle was still tied to the surfboard. As a result, he tripped over his surfboard and fell right into the water. Kurt inwardly groaned after he was underwater. Now, his Armani jeans were all wet, so were his sketches in his notebook. Could the day get any worse? As if on cue, the water around him started bubbling. After a while, the bubbling just stopped. Kurt's heart skipped a beat when he realized what just happened to him. His legs were gone. He had a tailfin. A gleaming, long, bright blue one with scales and everything. Was that a joke or something? Did he still dream? Suddenly, the memories of what happened the day before, came back to him: that dumb midnight hike, Blaine falling down the hole, that weird volcano and the bubbling water, the bright light, then… nothing, like a blackout. Kurt frowned. He needed to talk to Blaine, immediately. He wanted to swim up, but it wasn't working. He looked down. The surfboard rope, which once fitted his ankle perfectly, was now to tight for his fin. On top of that, the surfboard was stuck between a rock and the pier. Kurt tried to free himself from the rope, but the opening of the leash was also stuck. He groaned and bubbles escaped his mouth. Why did the god he didn't believe in or whatever high force that existed hate him that much?

Time passed and Kurt was still struggling against his surfboard. He wondered why he didn't need to breathe yet. Normally, he could hold his breath no longer than forty seconds, but now, maybe half an hour passed, and he was still fine. He also noticed that his vision underwater was perfect. What the heck had happened to him? And more importantly: How could he free himself? He didn't know how long he could hold his breath now, but to be honest, he didn't want to tempt fate. He had to get out before he drowned. Kurt tried to pull the surfboard away, but in vain. He sighed. That day sucked.

In the meantime, Blaine, Mike and Artie finally decided to go to the beach. On the beach, Puck and Finn joined them and dragged them to the volleyball place. At the moment, Blaine, Mike, Puck and Finn were playing volleyball with Artie being the referee. After some time, Rachel, Tina and Mercedes came running to them. "Guys? Have you seen Kurt?", Rachel asked breathlessly. Blaine dropped the ball. "Did he disappear?", he asked worriedly. Tina nodded. "We were on the pier where Brendan, the surf instructor showed us how to surf. We went ahead to the beach and left him behind, but he never appeared. He just vanished, and so did his surfboard." "Maybe he went down the beach?", Mike reasoned. Mercedes shook her head. "We asked everyone on the beach, there where even people sitting next to the pier. According to them, after the four of us left the pier, nobody else did. However, the pier is pretty abandoned now because it's dinner time.", she explained. She took a phone out of her purse. "We only found his phone on the edge of the pier." Blaine was deep in thought. Where could Kurt be at the moment? If he never left the pier, where was he then? He couldn't just fly away or something. Unless…What if the same thing that happened to him happened to Kurt as well? Blaine excused himself, claiming he needed to pee and went to the pier. At the end of the pier, he went to the edge. There were no railings, so theoretically, he could have fallen down. Blaine squinted to the bottom of the sea. Thanks to the waves, the water wasn't that clear and he couldn't see that much. However, he thought he had seen a movement deep down in the water. Blaine frowned. What was Kurt doing there for one hour? Why didn't he come up? He would find out, but first, he needed to do some preparations. Blaine turned around and ran down the pier and to his hotel room.

A/N: Yup, I've borrowed some elements from H2O for this fic. However, this is not really a crossover because none of the characters will appear and I changed a lot of things. There is no need to know the H2O series as everything will be explained anway. I hope you will like it ;)
