The Pigs are non playable characters that appeared in Spyro: Enter the Dragonfly. They were taking a vacation on Luau Island when they were suddenly captured by the Riptocs and set to become their dinner that night. Had Spyro and Sparx not visited the island, they would have been eaten before Ripto's defeat.
Trivia
The names of the Pigs have a connection to a type of food (Chili, Hammy, Hamlet, Porkins).
When you are not talking to them, they have the same voice as the Professor.
They carry around a map of the island they are on. The front of the paper can be seen in deep graphical detail if the player gets a good view.
