Video prompt: A colorful kingfisher darts from its perch, diving sharply to pluck a fish from a pond's surface before returning to its branch.
Defect: Deformation (any reason involved with a movement)
Explanation: The **bird's torso** undergoes **severe deformation**, particularly noticeable in its **legs**, which appear unnaturally bent and stretched. The changes in the bird's body shape are highly irregular and inconsistent, deviating from the expected stable structure of a bird in motion or at rest.
