A boy with black hair and sea green eyes was sat on a bench in Amity Park Central Park. A girl with blonde hair and startling grey eyes sat to his right and a man with thinning brown hair, a scraggly beard and a tweed jacket sat in his wheelchair to the left of the boy.

"Chiron," The boy said. "You said Grover would meet us here, right?"

"Yes, Percy, I did," Chiron, the man, said.

"So where is-" Percy started.

"Shut up, Seaweed Brain, I hear hooves!" The girl said.

"Annabeth, Percy, Chiron," Grover bleated as he grabbed the two sat on the bench in a bear-er-goat hug.

"G-man, my main satyr, what have you found?" Percy asked.

"Two half-bloods and a third-blood," Grover said.

"Where are they?" Annabeth, the girl, asked.

"The only high school in Amity Park, the name really suits this towns status, Casper High," Grover said. He then bleated "only one problem..."

"And that is...?" Percy interrupted.

"Let him finish, Seaweed Brain," Annabeth said. "Go on."

"Casper High is the most haunted place in this own, and that's saying something!" Grover finished. They small group talked about the three Demigods they were here to collect, until Percy's Seaweed filled brain picked up on something;

"Wait a second! What's a third blood?" Percy asked.

"Well he's a half-blood, and a halfa but since you can't be three halves of something, he's a third god, a third ghost and a third mortal," Grover answered. The sun chariot was setting and the moon chariot was rising, as the sky became darker.

"Where are we staying?" Chiron asked.

"The thing is, bla-ha-ha, we're staying at one of the half-blood's," Grover said, bleating half way through.

"How did you manage that?" Percy asked.

"I told her I was a vegetarian," Grover answered. "And that I had no where to stay."

"So where is she?" Percy asked.

"I think the question is 'where are they?' Seaweed Brain," Annabeth said. "And 'they' are there!"

Three kids on electric scooters were riding as fast as they could from a hydra! The boy in the middle said something to his friends, and they came closer to him and grabbed his handle bars. He then turned around and shot a green laser, that seemed to come from the palm of his hand, at the hydra.

The blasts hit the hydra in the chest but only slowed it down. "They're not going to sustain that much longer," Annabeth said. "They need help!"

"Whatever you say, wise girl," Percy said, before Annabeth could say anything else Percy had ran towards the hydra with one hand pulling out his pen, the other ready to take the cap off. "Hey ugly!" He shouted waving the pen-turned celestial bronze sword above his head. The hydra swung seven ugly giant snake heads towards Percy and seemed to decide that Percy was more of a threat than the kids on scooters.

"Chiron can you and Grover get those kids, please?" Annabeth asked as she pulled out her bronze knife from her jeans and followed Percy into battle. "Percy, do not chop the heads off!"

"Yeah, I know Annabeth," Percy answered.
