The whole underside is black including the suction cups where it can hold on rock walls and even hunters. It crawls on the ground of the lake and swims only when attacked. It uses ice element to freeze the foes. Trocus can rotate to give enemies many hits one after another. It feeds of Macory that it breaks up with its beak. It's the juvenile form of the Troculid. Sometimes the Antarctic Ground lake is full of Trocus. That's when their prey, Macory, have their Mating Season in the lake. This is a very important event for the Troculid population.
