This egg was only available in Egg Cave's Cash Shop Park for January 2013.
A magical snow dust surrounds this egg. This magic dust delivers an ice cold sting to any predator that might seek to harm the egg.
The Biwo enjoys the colder climate of the southern part of Ark. They are creatures that are only active at night and sleep during the day. Packs of them are quite easy to spot at night because the Biwo's eyes glow bright blue.
In terms of temperament, Biwos are friendly to humans, although they do not regularly associate with them, nor do they like being treated as pets. They are noble and proud creatures that are strongest with their own kind. As honorable creatures, they frequently patrol the southern forests of Ark and put an end to the evil doings of dark creatures that lurk in the forests.
Legend tells that if you have a good and honest heart and are found in trouble in the forest, a Biwo will find you and come to your aid.
