Hello everyone. So this will be the first chapter of percy's life. Now unlike with other growing up on Olympus stories this will not start with him as an adult this will start with him and Thalia growing up on Olympus as little kids. Also Nico and all the demigods will eventually make an appearance.

I do not own.

All of Olympus was in a hurry one morning. Every nymph, every minor God, every muse, and entity was running around in a frenzy. They knew what today was. It was the Birthday of the two demigods. Percy and Thalia. The entire mountain was having a party. Even Hades was coming. Every being that had met Percy and Thalia had instantly fallen in love with the two. There were jokes saying that those two were Olympus's finest treasures. It was pretty well known that once they reached a appropriate age they would be turned to Gods. Though it was never out rightly said everyone knew that it was true. Even the Percy and Thalia knew that it would happen. Everyone knew that it would happen because those two demigods were more powerful than Hercules himself. Thalia was the sky princess. She was Zeus's and Hera's heir to the throne. Though it was almost unheard of Hera actually liked Thalia and Percy. She acted like a mother to Talia and a aunt to Percy. Everyone had bonds with those two.

There was a bit of a story concerning Thalia though. You see her mother, a Hollywood star, didn't want to be responsible for a child. So one day she drove into LA and dropped Thalia off at a casino. I know not the most responsible thing to do but she was drunk. That casino was called the Lotus Hotel and Casino. She stayed there being pampered by the staff for five years. Until Zeus tracked her down and brought her to Olympus. While Thalia was in the Lotus Hotel and Casino Jason was born. At this point Hera, outraged that Zeus had a child, for she had not known about Thalia, demanded that the child be given to her. The child was raised as a child of Rome and never knew that he had a sister at all, just as Thalia had never known about her brother. Because of her background Thalia and Artemis had a great time together. They would run around Olympus and shoot boys in the butt. Sometimes Percy would join. Though more often than not he accidentally shot himself. But enough about that. This is what happened at their Birthday party.

Athena had been given the task of distracting the two young demigods with tales of the odyssey, while all of Olympus set up the surprise party. The muses were to play, the nymphs to dance, and every god had something that they brought to the party. The demigods were turning five.

It was two 'o' clock. The lesson with Athena was over. Percy and Thalia made their way down the corridor to the great hall. The Gods had summoned them for some obscure reason. They opened the huge double doors, only to be almost pushed backwards with the force of the yells coming from the inside.

"HAPPY BIRTHDAY!" Thalia and Percy just stood there with a look of shock on their adorable faces. Then they both started blushing. And giggling. And looking very surprised. Suddenly the Gods weren't able to take the picture of cuteness anymore, they all ran over and swept the demigods up. Hera got Thalia first and Amphitrite somehow got a hold of Percy. They didn't stay in their arms for very long though. All the goddess and gods started clamoring for a chance to hold the angels. Suddenly Percy and Thalia exchanged winks and asked in innocent voices.

" present time? Cake?" that subtly remained the Olympians what they were here for. All of the Olympians exchange disappointed looks and set the two friends on their feet. The minute the feet touched the ground they were off and running and scampering over to the seven foot high cake. Percy grabbed a huge knife and wielding it expertly he sliced a smooth piece of cake. It was rather large so after a couple bites he ended up giving the rest to his dad. Everyone swarmed around the cake to eat some of it.

Then Thalia started shrieking. Everyone turned toward her in a panic. What they saw made them want to laugh. Thalia had started opening presents, inpatient girl that she was, and after she tore open her father's gift she had come upon a silver bracelet. After she touched it, it somehow expanded into a replica of Athena's shield. The false medusa head was so frightening that several Gods took a step back. She was leaping around and waving it in their faces with a look of glee on her face. She raced over to her father and hugged his legs very hard. Then she raced back to the rest of her presents. Soon she was surrounded by a pile of wrapping paper larger than she was. The only other huge thrilling gift was hers from Hera, and Percy's. Hera had given her a crown! It was delicate and platinum with sapphires embedded ( picture on profile) it fit snugly on her head. It showed everyone that cared that she was important and that she was the sky princess. Percy's was a sloppy little picture frame that he had made himself that surrounded a picture of the two friends. It had seashells and lighting stickers all around the frame. Thalia loved it. After she was done with all her presents Percy started opening his. His first present was in a long box covered in wrapping paper that was from his father. He ripped it open to find a ballpoint pen nestled in satin. He shot a look of confusion at his father who mimed pulling off the cap.

He placed a small chubby hand on the cap and pulled only to find that he was no longer holding a pen, but a sword. He stared in awe at the glistening blade and ran his hand down the surface. He looked up at his father his eyes shining in excitement he dropped the sword and ran over to his father and hugged his legs in a move similar to Thalias. Then he opened Amphitrite's. In the package was a crown, like Thalias. Percy's was a lot less gaudy than Talia's seeing as he was the second prince of the sea. His brother Triton being the heir. It was silver and had aquamarine and pearls embedded. He plunked it on his head, much to the amusement of the Gods and continued to tear into his presents.

All the presents had been opened, the cake eaten, and now it was time for the music. The muses struck up a tune and everyone started to boogie. Personally I believe that Thalia and Percy were traumatized from seeing Apollo dance. It was about eight 'o' clock when Thalia and Percy started to get sleepy. But they didn't tell anyone, because they didn't want to have to leave the party. The two were sitting on a couch in the corner of the room. Suddenly Percy slumped over onto Thalias shoulder and fell asleep. Twenty minutes later Aphrodite noticed that the cousins had fallen asleep on each other and started cooing. Everyone turned to see what she found adorable and started cooing and awing as well. Hera ran out of the room in search for a camera. After about twenty pictures were taken the two sleepy demigods were put in their rooms and everyone retired for the night.

But that morning when Hera went to wake up Thalia she found the two demigods curled up around each other sucking their thumbs and cuddling. After about a hundred pictures, she left them deciding to let them sleep a little more.

Fluff. That is all I have to say. I didn't want to just start this story on when they had suddenly grown up. I want to show you how Thalia and Percy developed. I have the next couple chapters all planned out and I know exactly where this story is going. I hope you enjoyed the fluff. REVIEW! Totallyawesome out.
