This egg was only available in Egg Cave's Cash Shop Park for December 2011 & 2020.
Adarna eggs are incubated in snow. Because of the rareness of snow in Ark, Adarna eggs are also very rare.
Adarnas are a rare type of peacock that come out of hiding during the winter season. No one knows why they hide during non-winter months. Naturally, they are referred to as the Christmas peacock. It is typical of Ark residents to put an Adarna on top of their Christmas tree.
Adarna are commonly found frolicking through the snow. But whenever it snows, they shed their feathers entirely. But naked Adarna are not commonly seen because their feathers regrow incredibly fast.
