Porkpie

Porkpie is one of Blackjack's Pegasi friends along with Guido.

The Titan's Curse
Porkpie helped Blackjack and Guido take Percy, Annabeth, and Thalia to Mount Olympus from San Francisco, California and Mount Orthys.

The Battle of the Labyrinth
Porkpie was one of the pegasi along with Blackjack, Guido, and an unnamed pegasi that responded to Percy's call when they needed to get back to Camp Half-Blood immediately from New York City (Manhattan) so that they can warn Chiron about the impending invasion of camp by the Titan Army to destroy camp before waging war on Olympus and the Olympian Gods themselves.
