Penguins
From chakuwiki
Penguins are the natural inhabitants of Geraptiku, from before it was detached from Oz.
They resent the de-watering of the land, but don't do anything to help with the import of air. They have become impermeable to poking so as to not lose any of their own holdings of this precious resource, even though they haven't done anything to increase the total amount.
Many people think that the penguins are quite selfish and unreasonable, while still more think that they are shellfish. The debate is ongoing, and no conclusion will be mentioned here at this time.
The singular of "penguins" is "penguin".
