Ping is one of two penguin bards that seem to be working with the Killer Gentoo Penguins. They reside in a musical room in the KGP headquarters on the Iceberg. Ping and Pong both play parts in the quest Cold War. Unlike the other agents of the KGP, these penguins are not evil and only enjoy playing music and composing songs.
During Cold War, players have to bring them cowbells and a set of penguin bongos. A cutscene appears, in which the two penguins are nearly thrown into solitary by an agent for being too loud.
