2. Hoary Hedgehog (5.04)
There are 17 species of hedgehogs in parts of Europe, Asia, Africa, and New Zealand; none are native to Australia or North America. These primarily nocturnal mammals tend to be insectivores and are perhaps best known for their ability to roll into a tight ball when threatened. Other names for the hedgehog include urchin, hedgepig, and furze-pig, according to Wikipedia.
Hoary Hedgehog, meanwhile, was released in April 2005 and added features including an update manager and APT authentication; and suspend, hibernate,") and standby support.
