Video prompt: a cute black and white cat playing with a cardboard box, which is a common activity for cats. The cat appears to be enjoying its time, exploring the box with curiosity and playfulness. The cat's actions show that it is having a good time and engaging in natural behaviors that cats find entertaining.
Defect: Deformation (any reason involved with a movement)
Explanation: The kitten's face and tongue appear blurry and indistinct, with noticeable jittery shape distortion as it moves. This shaking effect causes its facial features to appear unstable and unclear, giving an unnatural appearance to its movements.
