The Killer Penguin ("Eudyptes omnicidus") is a very large fictional bird. It is an obtainable animal in Zoo Tycoon 2, although its origins date back to Zoo Tycoon. The killer penguin is an extremely large member of the penguin family Eudyptes, identifiable by the presence of yellow crests of feathers above their eyes. Superficially, the killer penguin resembles a very large Rockhopper Penguin, but has glowing yellow eyes and sharp teeth. As its name implies, the killer penguin is a savage predator and will hunt and kill any other creature it comes across, often purely for fun. The origins of the killer penguin are unclear. Some say they were once native to the island of Madagascar, but they seem to most commonly show up during failed attempts to revive other extinct animals. Despite their fearsome behavior, killer penguins do sometimes enjoy a peaceful life and are quite intelligent, often sneaking into scientific laboratories. Regardless, it has such a reputation that many zoos have been unable to contain them and warnings exist amongst the community of zoos donating their killer penguins to others for free.
