KGP Agents are penguins encountered during the quest Cold War. They are agents for the KGP (Killer Gentoo Penguin), as implied by their examine text.
Besides Pescaling Pax, they run the various activities on the Iceberg. One guards the entrance to the base under the Iceberg, and will not let anyone in without an ID card. There is also another KGP Agent guarding the entrance to the war room and the Icelord cage.
During Cold War, players must provide cowbells and a set of penguin bongos to Ping & Pong, to be able to distract the guard, and enter using the control panel he is guarding.
