Animate the dancers lifting up their knees and planting their heels in a rapid sequence of 4 strikes per second, as if they would perform a very fast moonwalk on the spot. Intensify the lifting of the knes, so that the motion reaches as high as the waists of the dancers. Their arms and hands perform rave stabs in the air in sync with the movement of the legs. Keep the two feet of each dancer seperated, so they don't blend together. Animate the dolphins in the background, bouncing slightly up and down in the same rythm as the dancers. Keep the camera static and the background elements in place.
