She and the rest of Flowglow are getting lessons as well so they can participate in 3D lives, Fes, and concerts once they are promoted to full members and receive their 3D models. Although, I think I remember Su mentioning she has dancing experience, so this might be FlowGlow specific training or her learning dances with the rest of her gen.
