This egg was only given out in January of 2012.
Bliz eggs require freezing temperatures in order to hatch. As a result, they can only be found buried under several feet of snow. Because they will die quickly after thawing, Blizes are difficult to raise.
The Bliz is a spectral reindeer that is often referred to as the "blizzard mirage." Typically only spotted by lost Arkians in snowstorms, Blizes only appear when one loses all hope of survival. However, they tend to disappear when approached. There is a one-in-a-million chance that a Bliz will allow you to ride it to safety and those lucky citizens are often envied by the rest of the population. In fact, there have been reports of Arkians purposely hiking in dangerous blizzards on the off chance that they will catch a glimpse of a Bliz.
