An Arckip's peculiarly-shaped cheek fins are as rigid as the beds of riverside rocks they make their nests amidst. These fins can resonate with their cries and help them to travel further to communicate with others of their kind.
On land, it can powerfully lift large boulders by planting its four feet and heaving. It is described in mythology as the Pokémon that shaped the universe with its 1,000 arms.
