Kling 2.5 Turbo (pro) The boy and girl take their hands out of their pockets, turn to face the audience, and dance a fast, energetic rock 'n' roll, smiling, quickly and rhythmically moving their feet and arms simultaneously, clapping their hands first to the right, then to the left. They alternately step their right and left feet out to the side. Their movements are fluid and harmonious, in time with the music.
