Pengum
From PinataIsland.info, the Viva Piñata wiki
A Penguin species of pinata is mentioned in the episode guide in the description of an episode called "The Abominable Jeli". The Jeli has gotten much attention since, and many hope it will be a future download. However, the Penguins mentioned in the episode guide have not had much attention. This species may exist in the form of a future Downloadable Content for the game, but it is unknown if it will.
