Tank is one of the Snow Minions in Card-Jitsu Snow. Tank is large, strong, but not very smart. He wields a snow flail, and used sleds as armor and shields.
As mentioned in a post on the Club Penguin Blog, Tanks favorite food is "farmer's breakfast (eggs, sausage, bacon, hash browns, toast, pancakes, extra sausage, extra bacon)". His favorite "dance" is his default animation in Card-Jitsu Snow. Additionally, he supposedly growls when he hears Sensei's name.
Unlike the other snow minions, Tusk does not have a carrot for a nose or sticks for arms.
