Extension to Penguin Hide and Seek, which consists of a 3-point Penguin Spy that requires the seeker to be wearing a ring of visibility to be able to spot it. The penguin randomly teleports every few minutes. It can also travel across the water and over mountains to any part of the Gielinor surface.
