Video prompt: A dancer is performing a ballet routine on a stage, wearing a white tutu under bright spotlights.
Defect: Deformation (any reason involved with a movement)
Explanation: The ballet dancer's body twists unnaturally, resembling a noodle rather than maintaining a stable human form. Additionally, the legs appear entangled and distorted, taking on the appearance of two intertwined ropes, which disrupts the natural alignment and posture expected in ballet.
