Chiron is fired from his job as camp activities director as the gods suspect him of poisoning Thalia's tree, and leaves Camp Half-Blood to join the Party Ponies in the Everglades. He hoped they might know a cure to the poison that he himself had forgotten. The Party Ponies (Florida Chapter) rescue Percy, Annabeth, and Tyson from the Princess Andromeda. They then take them to Camp Half-Blood.
Chiron leads the Party Ponies as reinforcements in the Battle of Manhattan. The groups mentioned were the South Florida Chapter, Texas Chapter, Hawaii Chapter, New Mexico Chapter, Rhode Island Chapter, South Dakota Chapter and Delaware Chapter.
After the battle, Percy cannot see any, meaning that they were either killed or ran away.
Rachel Elizabeth Dare mentions them during the meeting with the Romans, claiming that a waking Gaea had created a large fist in Colorado and swatted the Party Ponies like flies. Reyna questions who the Party Ponies are, but Rachel simply says that it is a long story before moving on.
