What it was like for Poseidon to raise Percy and Toothless

One year old

Poseidon's POV
It was Percy's birthday. I never ran a birthday party because well no immortal ever celebrates their birthday. But since Percy isn't immortal, and this is the first birthday I've made, I want it to be the best. I got help from Hermès, Aphrodite, Hades, Apollo, Hephaestus, Dionysus, Demeter, Hestia, Artemis, Persephone, and Amphitrite. Tritons still grounded. Aphrodite and Persephone would make sure Percy never saw the party before she had to. Demeter and Amphitrite would bake the cake and other sweets. Hermes would send invitations cause it seems Aphrodite told more people, I don't know why I trusted that gossip. Let's see she told Eros, Hymenaios, Ganymede, the three Charites, the Erotes, and my mother, Rhea. Dionysus would help with the drinks, Artemis would make sure Zeus doesn't find out cause the party is in Central Park. Hades gathered some of the Confederate skeletons to help decorate. While we were decorating, a loud cheery voice rang out. "Where is she?" We looked to see a woman. The woman wore tinted glasses that were changing from orange to purple, she had a silver-and-gold tiara in her braided black hair. Her batik dress was swirling with images of fern fronds, her arms and hands were covered in henna tattoos. She wore a macrame belt that cinched her waist, around her neck was a chain with a brass peace symbol. She had green eyes.

This is Rhea.
"Mother!" Hades yelled happily. Hestia, Hades, and I ran up and hugged her. "Oh, I am happy to see all of you!" Mom exclaimed. "Now where's the birthday girl?" She turned to me. "She's actually in her room right now. I want her to be distracted for a little while before her birthday." I told her. She nodded and left to see Percy.
Rhea's POV
I entered my son's palace and happily ran to my granddaughters room. When I opened the door, a giggling, dirty, one-year-old ran up to me. "Rhea! What are you doing here?" Persephone said looking exhausted. "Hermès sent me an invitation." I looked down at the girl, who was smiling at me. "Is this the Percy you told me about, Aphrodite?" I picked up the girl. "Yes, and do you mind taking care of her? She's more energetic than we thought." Aphrodite was also exhausted. "I don't mind. I miss this." I said. Aphrodite and Persephone left. I went into the bathroom and ran a bubble bath, I checked the temperature to make sure it was okay for a baby. I took off Percy's clothes and placed her in the bath with some toys. "Dada." She said splashing the water. "Yes, dada would love to see you all clean and beautiful for your birthday." I said as I put shampoo on her head. Since Percy could breathe underwater and therefore cannot drown, I left her in the bath for a while. I went to choose a dress for her. As I was choosing, my son, Poseidon, came into the room. "Hey, mom." He said. "Hello, Poseidon." "What are you doing?" He asked walking over to me. "I'm giving Percy a bath, and putting her in a dress for her birthday." "Oh, well, uh Percy loves the color blue." I put my hands on my hips and raised an eyebrow. "Really? How do you know?" I asked him. "Well, she likes to eat blueberries, she at first didn't like pancakes but did when I added blue food coloring. Blue was her first word," he was counting all of this on his fingers, I stopped him. "Ok, ok I get it, and by the way where's that merman son of yours?" I asked him, picking up a blue dress. "He's grounded." He said abruptly. "What! Why?" "Because when I got Percy, Sally, her mother had given her to me cause a man she married was becoming too abusive. Triton kidnapped her from her room, and placed her in an abusive household. So I grounded him for two years." "You grounded him over sibling rivalry?" "What?" "All siblings have a bit of rivalry between them. You and your brothers have yours, Percy and Triton have theirs. Yes, it was cruel where he put her, but he's going to get jealous of her again." I explained to him. "So, you think I should unground him?" "Yes," I said nodding my head. "Ok, but before I go, can I see Percy." He headed towards the bathroom door. I stopped him. "No, you will see her at the party when she's nice and clean." "But mom-"  "No, buts, you will see her at the party." I put my hands on my hips. Poseidon looked at the door then back to me, with a pout on his face he said. "Fine." He left shortly after. I went back into the bathroom, Percy was playing with the toy boat. I picked her up out of the bath and dried her off. I dressed her in a royal blue dress with white shoes.

I put a little white bow in her hair. "Grandma!" I heard a boy yell. I looked to see Triton. "Oh, hello, Triton." He hugged me, I hugged him back with Percy in my arms. "Hey Percy." Triton started tickling Percy, who laughed and laughed. "C'mon, we don't want to be late for Percy's birthday." I said. When we got to Central Park, it was nighttime. But we knew where the party was because of the fairy lights and colorful balloons. All the gods that knew Percy existed were there, including some nymphs and satyrs. I noticed my stepson Chiron was here too. Chiron is a centaur.
The nymphs, water and woods alike, gathered around trying to get a good look at Percy. She didn't seem to like it to much. She swatted them away as best she could, but when that didn't work she hid her face in my neck. Finally, I said. "Alright, alright, enough girls. You're scaring the baby." They all scattered away, talking about how cute Percy was. I found Poseidon talking to Amphitrite, when he turned his head, his eyes first laid on Percy, who was trying to grab a blue cookie. He came up and grabbed her, giving her a ton of kisses. "Now, if I remember you and your brothers promised to never have any kids?" I told Poseidon. "Yes, we took an oath, but you know we couldn't stop meeting women, and the one who gave birth to Percy, I just couldn't resist." "Why didn't you invite Zeus or the other gods and goddesses?" I asked him curiously. "Maybe it's because he tried to kill my two kids back in Italy, instead he killed their mother." Hades said joining in. "Oh, did he kill Percy's mother too?" "No, Sally was killed by her husband." Poseidon said sadly. "Well, it would've been better than whatever Zeus had in store for her." Hades commented. "Hades, where are your kids?" I asked. "Somewhere safe. Certainly not with me, I put them somewhere Zeus can't touch them." "Alaska?" I said aloud. "No, and I'm sorry but I can't tell you mother." Someone said. "No, but maybe you could tell me." We looked to see Athena. I went out to hug her, but she stopped me. "I'm sorry Rhea, but I need to talk to Poseidon." Athena said. Poseidon held Percy tightly. "Poseidon, give me your daughter." She said holding out her arms. Poseidon shook his head no. "Athena, Percy is young, and she should stay with Poseidon." I told her, putting a hand on her shoulder. "No, she doesn't, when she turns sixteen she could be Olympus's downfall." Athena retorted. She was being loud, everyone was looking at us. "She is turning one today!" I started to yell. "She is just a baby! You don't even know what she'll be when she grows up or if she'll be Olympus's downfall. A prophecy does not determine how a child grows up, her father does. Now, you can either go and tell Zeus and be the reason a baby is dead or you'll let Poseidon keep her and watch her grow." I crossed my arms. Athena looked to Percy, to me, to Percy again. Percy cooed and looked around. "Fine, but if she-" "She won't." Poseidon said truthfully. Athena nodded and left. Percy's birthday went as planned. We sang Happy Birthday and Percy was able to stuff her face with cake. When we went to my son's palace we got Percy to open her presents on her own. She got dresses, toys, shoes, art supplies, I gave Percy a stuffed animal of a lion. She slept like a baby with it.
