Amphitrite put baby Percy into a crib. They were on Mount Olympus, and it was a celebration for Percy's birth.
"Shh..." Amphitrite said. "Behave, Percy."
"He's so cute!" Poseidon said.
Percy splashed his father in the face.
"And he has the power of his father!" Amphitrite smiled.
Hermes flew over, using his winged sandals, and handed Amphitrite some flowers. "Congratulations! These are from Orpheus!"
Percy reached for his fathers trident and started to play with it.
Poseidon snatched it away. "Now now, you're too young for that, Percy."
They looked around at the wonderful party, that Zeus had thrown, of course. Amphitrite placed a hand on Poseidon's shoulder.
"Even if it's not our party, Percy is our son." Amphitrite said. "So have a good time, dear."
"Your right." Poseidon smiled. "On behalf of my son, I want to thank you all...for your wonderful gifts!"
"What about our gift, dear?" Amphitrite asked.
"That's a surprise!" Poseidon said, and whistled.
Out flew a baby black Pegasus.
"His name is Blackjack, and I hope he'll be a great friend to you son!" Poseidon smiled.
Blackjack flew down and cuddled with baby Percy.
All would have been well, but then in came a party crasher—Hades.
"Hello everyone, how is Olympus?" Hades said. "And look its a little seaweed, son of Poseidon."
Hades grinned, but no one laughed, except Zeus, who always underestimated Hades.
"Good to see you brother! Why don't you join us?" Zeus said.
Poseidon, however, took a step to protect his son, and Blackjack growled.
"I would, but I'm rather busy in the Underworld. Thanks to you..." Hades said. "Not that I'm bitter. Not bitter at all."
He faded into the shadows.
