A sport that takes place in the ice lakes of the north Adrarct has a preparation technique known as bowling while preparing for the sport of Skullsliding. Penguins are hunted by the younglings and taken back to the villages to have their bodies used fully for various food and material. The tops of the skulls of these birds are collected and intricately carved with patterns and details, sometimes stories are inscribed around the small bowls made from the skull tops of the Adrarct birds.   A concave stadium is carved into the deep ice and smoothed out. The bowls are then spun around the inside of the ice in a circular motion. The bowls travel the large concave surface crashing into each other. Usually around 20 bowls are slid at the same time. These bowls crash into each other and bounce around. Sometimes these bowls shatter, disqualifying the participant. The last bowl remaining unshattered or the last one spinning wins the competition. The larger penguins are hunted not only for their food source, they also tend to have thicker skulls good for Skullsliding.
