Video prompt: A troupe of seals basking on sun-kissed rocks, occasionally slipping into the sea with a splash to cool off and play in the ocean's refreshing embrace.
Defect: Deformation (any reason involved with a movement)
Explanation: The seal’s head and tail swap positions, with the head transforming into the tail and vice versa. This sudden and unnatural change in body orientation is impossible for a real animal.
The seal's movement looks unnatural, as it appears to be using its limbs to walk in a way that resembles a land animal rather than a seal's typical motion.
