First appearing in the episode "The Lord of the Fleas" (an obvious parody of Lord of the Flies), Piggy is a small penguin with thick eyeglasses who can often be seen sporting a pig mask. He is often seen in the company of a larger and deeper-voiced penguin as they take part in the bizarre circumstances of the show. Often, in a running gag, Piggy will discover something strange and attempt to inform his larger companion, who then responds by saying "Shut up Piggy!" Piggy has a distinct British accent, another reference to The Lord of the Flies. Piggy returns several times in quick cameos and occasionally takes a larger role.
