Moose

The Moose, like the Polar Bear, is a mystery. Evidence of the moose have been found all over the island, but it unknown how they got there because moose live near the North Pole. It is possible that a moose floated to Penguin Island on an iceberg like Herbert did, but this is unlikely.

Examples of Mooses in Penguin Culture
In the Ski Lodge, there is a moose head hanging on the wall. He has been decerated for several parties. Also, both the Blue Team and the Red Team have a moose mascot, shown in many plays at The Stage, named Zues and Jupiter respectively.
